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

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!
A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles
together. What is the final velocity of the two vehicles?
(Please show work)
Answer:
50 x 3000 = 150000/4000 = 37.5
37.5 I think.
Explanation:
Hope this helps!
A 3000 kg truck travelling at 50km/hr strikes a stationary 1000 kg car, locking the two vehicles together, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.
We may use the concept of conservation of momentum to calculate the final velocity of the two vehicles after the collision.
The total initial momentum (P_initial) is given by:
P_initial = (mass of truck) * (initial velocity of truck) + (mass of car) * (initial velocity of car)
P_initial = (3000) * (50) + (1000) * (0)
The velocity:
Vt = 50 * (1000/3600) = 13.9 m/s
Vc = 0 = 0 m/s
P_initial = (3000) * (13.9) + (1000) * (0 )
P_initial = 41700 kg·m/s
P_initial = P_final
41700 kg·m/s = (3000 kg + 1000 kg) * Vf
41700 kg·m/s = 4000 kg * Vf
Now Vf:
Vf = 41700 kg·m/s / 4000 kg
Vf ≈ 10.43 m/s
Therefore, the final velocity of the two vehicles after the collision is approximately 10.43 m/s.

How far will a force of 6 x 10^3N stretch a spring with spring constant 3 x 10^4 Nm-1 ?
Answer:
0.2m
Explanation:
F = 6 x 10^3N
k = 3 x 10^4 Nm-1
x = ?
from Hooke's law, F = kx
x = F/k = 6 x 10^3 ÷ 3 x 10^4 = 0.2m

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.

Explanation:
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.

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.
