a. 178.5 m
b. 69.97 m/s
c. 7.14 s
Further explanationGiven
height = 250 m
vox = 25 m/s
Required
distance from base
vertical speed(vy)
time to reach ground
Solution
voy = 0
h=voy.t + 1/2 gt²
h = 1/2gt²
250 = 1/2.9.8 t²
t=7.14 s
x = vox.t
x = 25 x 7.14
x = 178.5 m
vy = voy + gt(voy=0)
vy = 9.8 x 7.14
vy = 69.97 m/s

How are reversibility, time, and entropy connected
Answer:
As one goes "forward" in time, the second law of thermodynamics says, the entropy of an isolated system can increase, but not decrease. ... Thus, entropy measurement is a way of distinguishing the past from the future.

F = 6.0 x 10⁻⁸ N
Further explanationGiven
mass of 2 dump trucks = 1500 kg
distance = 50 m
Required
Gravitational force
Solution
Newton's Gravity Law:
[tex]\rm F=G.\dfrac{m_1.m_2}{r^2}[/tex]
with F = gravitational force,
G = gravitational constant,
m1, m2 = mass of object,
r = distance between two objects.
Input the value :
F = (6.67.10⁻¹¹N.m² / kg² x 1500²) : 50²
F = 6.0 x 10⁻⁸ N

Ranjana has average velocity 3.2 m/s
How long does she take to cover a displacement
of 256 m
Answer:
t= 80 seonds
Explanation:
Given that,
The average velocity of Ranjana, v = 3.2 m/s
We need to find how long does she take to cover a displacement of 256 m. Let she takes t time.
We know that,
Average speed = distance/time
So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{256\ m}{3.2\ m/s}\\\\t=80\ s[/tex]
So, she will take 80 seconds to cover a displacement of 256 m.

A force of 20 N acts at an angle of 30° to the
horizontal. Determine the vertical component
of the force.
A. 17.30 N
B. 11.50 N
C. 10.00 N
D. 7.50 N
[WASSCE Nov 2008 Qu 11
α=30°
F=20 N
Fh=F*cos(α)
Fv=F*cos(90-α)=F*sin(α) (vertical component of the force F)
Fv=20*0,5=10.00 N

An eagle flying 10 meters per second swoops down to the ground to catch a snake speed velocity or acceleration
Answer:
Velocity because it has both magnitude (10m/s) and direction (to the ground).
Explanation:
Velocity can be defined as the rate of change in displacement (distance) with time. Velocity is a vector quantity and as such it has both magnitude and direction.
Mathematically, velocity is given by the equation;
[tex]Velocity = \frac{distance}{time}[/tex]
In this scenario, an eagle flying 10 meters per second swoops down to the ground to catch a snake. Therefore, this is an example of velocity.

A train moves at 300 km/h. How far will it go in 5 hours?
Answer:
1,500 km
Explanation:
300 km/h
300 kilometers PER HOUR
So you want to see how far it will go in 5 hours, all you need to do is multiply the kilometers by 5. Since we know that per hour it's 300 km.
300 * 5 = 1,500
The train moves at 1,500 km in 5 hours.

Which one, mass or weight, would change if you were to travel to another planet or moon?
Answer:
The answer is weight.
Mass is constant, your mass, height and width won’t change. So that leaves weight.
what is the formula for acceleration?
Answer:
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
Explanation:
A meterologist made these observations one day:
• In the morning, anocean wave hit a shoreline every 15 seconds.
• In the afternoon, an ocean wave hit the shorlinie every 30 seconds.
Identify whether the ocean waves transferred more or less energy in the morning than in the afternoon.
Write your answer in complete sentences.
Answer:
They transfered more energy in the morning.
Explanation:
This is because, let me put this in simple words, you have more energy, you can run more laps around the track, right? This is the same with the waves. They have more energy, so they can crash aganst the shore more!
