Answer:
<h2>4 m/s</h2>
Explanation:
The speed of the ball can be found by using the formula

p is the momentum
m is the mass
From the question we have

We have the final answer as
<h3>4 m/s</h3>
Hope this helps you
Answer:
True
Explanation:
Gravity is a very important force. Every object in space exerts a gravitational pull on every other, and so gravity influences the paths taken by everything traveling through space. It is the glue that holds together entire galaxies. It keeps planets in orbit.
Newton's 2nd law of motion:
Force = (mass) x (acceleration)
Divide each side
by 'acceleration': Mass = (force) / (acceleration)
= (2,500 N) / (200 m/s²)
= 12.5 kg
Distance is the physical length travelled. While the displacement is the shorter distance between any two given points.
<h3>What is distance?</h3>
Distance is a numerical representation of the distance between two objects or locations.
Distance can refer to a physical length or an estimate based on other factors in physics or common use. |AB| is a symbol for the distance between two points A and B.
Displacement is defined as the shortest distance between the two points.
Sam determines the distance by doing the calculation as;
distance = speed × time
Hence, the Sam determines the distance and displacement by the respective formulas.
