14.8m/s is  minimal horizontal velocity must the cliff divers leave the top of the cliff is they are to miss the rock.

Ledge divers in Acapulco leap into the water from a 36-meter-high cliff. A rock protrudes 10.4 meters horizontally from the water, level. 9.8 m/s2 is the acceleration of gravity. If the cliff divers are to miss the rock, they must depart from the top of the cliff with a minimal horizontal velocity.

from above statements, we assume that

there is no initial vertical velocity, then we calculate the time it takes to reach the water, then divide the horizontal distance by that time to get the minimum required horizontal speed.

h=gt^2/2

h= 36 m

t = [tex]\sqrt{2h/g}[/tex]

put h = 36 m g = 9.8 m/s^2

t=2.7 second

Then the minimum required horizontal velocity is

The force constant of the spring is calculated as 0.57 N/cm.

Hooke’s law states that the force that acts on an elastic substance is directly proportional to the extension as long as the elastic limit is not exceeded. We know that the statement of Hook’s law can only apply to an object when the object is still within the range of elasticity. If the object has reached the point where it has become plastic, that is, the  object has completely lost all of its elasticity, then  we could say that the Hook’s law can not hold in such an instance.

Mathematically, we could write;

F = Kx

F = force that causes the stretching of the object

K = the force constant

X = the extension.

We know that in the plot of the force against the extension, the slope is the force constant. Taking two points on the graph, it is possible to obtain the force constant as follows;

By using the blackbody radiation formula, the temperature of the filament inside the bulb is changed by a factor of 10⁰'²⁵.

We need to know about black body radiation to solve this problem. The energy radiated by a black body object is proportional to the area and the fourth power of temperature. It can be determined as

P = A . e . σ . T⁴

where P is power, A is surface area, e is emissivity, σ is Stefan Boltzmann's constant ( 5.67 x 10¯⁸ W/m²K⁴) and T is temperature.

From the question above, we know that

P1 = 10 watt

P2 = 100 watt

T1 = T1

By using the black body radiation formula, the ratio of temperature is

T1⁴ / T2⁴ = P1 / P2

Hence,

T1⁴ / T2⁴ = P1 / P2

T1⁴ / T2⁴ = 10 / 100

T1⁴ / T2⁴ = 1 / 10

T2⁴ = 10T1⁴

T2 = ⁴√(10T1⁴)

T2 = T1 x 10⁰'²⁵

The solid pieces of lead with a mass of 29.92 g has a density of 11,164 Kg/ m3.

To find the density the given values are,

v = 2.68 cm3

m = 29.92 g

The density is a mass of a unit volume of a material substance. It is a physical quantity that expresses the ratio of the body mass to the volume it occupies.

Density is a scalar quantity.

The unit of density is kg/m³.

The density formula and the procedure we will use is:

ρ = m/v

Where:

v= volume

ρ= density

m= mass

Applying the density formula, we get:

ρ = m/v

ρ = 29.92 g/ 2.68 cm3

ρ(g/cm3) = 11.164 g/cm3

Converting the density from (gram g /cm3) to (kilogram/m3), we get:

11.164 g/cm3 * (1 kg/1000g) * (1000000 cm3/1 m3) = 11,164 Kg/ m

The average velocity of the student who walks 160 m east and 80 m west in 67 s is 1.194 m/s.

It is defined as the rate of change of displacement with respect to time.

Mathematically -

v = Δx/Δt

Given is a student who walked 160m east and then 80m west in 67 s.

Assume east direction as + x direction and west direction as - x direction, then →

Displacement 1 = 160 a[x]

Displacement 2 = - 80 a[x]

Displacement = Δx = 160 a[x] + 80 {- a[x]} = 80a[x]      

Time elapsed = Δt = 67 seconds

Where (a[x] is unit vector along x - axis and -a[x] along negative x - axis)

After 0.85s, the ball would be at the same height.

A ball is thrown upward from the ground with an initial speed of 23.4 m/s; at the same instant, another ball is dropped from a building 20 m high....  

We know that from the equation of motion,

h = u t + 1/2 at^2

So h = height, u is initial velocity and t is time, a is acceleration  

Now for the ball thrown upwards  

h = 23.4 t – 1/2 gt^2

23.4 t – h = 1/2 gt^2

Now for the ball dropped downwards

20– h = 1/2 gt^2

Comparing both the equations we get

23.4t – h = 20 – h

23.4 t = 20

So t = 20/23.4

The runway should be 253.5m for a light plane that needs to reach a speed of 39 m/s for takeoff.

The rate at which the speed and direction of a moving object vary over time is called as acceleration. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting.

In physics, acceleration is the rate at which the velocity of an object changes in relation to time.

According to Newton’s Second Law, the sum of all forces acting on an item results in its acceleration.

Meter per second squared (m s2) is the unit of acceleration used in the SI system.

We know from the equation,

V^2 = u^2 + 2as → 1

Here a = acceleration of the light plane

v = final velocity of the light plane

u = initial velocity of the light plane

s = length of the runway

Then we also know that

s = (v^2 - u^2) / 2a → 2

v = 39m/s

u = 0m/s

a = 3 m/s^2

Then substituting these values in equation 2,

s = (39^2 - 0) / (2x3)
