Answer:
<h2>1960 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
PE = 10 × 9.8 × 20
We have the final answer as
<h3>1960 J</h3>
Hope this helps you
In the simplest case, a force applied to an object at rest causes<span> it to accelerate in the direction of the force. ... for a massive body moving in an inertial reference frame without any other forces such as friction acting on it, a certain impulse will </span>cause<span> a certain change in its velocity</span>
