<h2>0.5 kg</h2>Explanation:
The mass of the object can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>0.5 kg</h3>Hope this helps you
The potential energy of the body is "200 Joule".
According to the question,
Mass,
- m = 10 kg
Height,
- h = 200 cm
or,
= 2 m
- g = 10 m/s⁻¹
As we know,
→ The potential energy will be:
=
By putting the given values, we get
=
=
Thus the above answer is right.

Answer:
3.65 x mass
Explanation:
Given parameters:
Time = 20s
Initial velocity = 0m/s
Final velocity = 73m/s
Unknown:
Force the ball experience = ?
Solution:
To solve this problem, we apply the equation from newton's second law of motion:
F = m
m is the mass
v is the final velocity
u is the initial velocity
t is the time taken
So;
F = m ( ) = 3.65 x mass
