Question
A 4.1-kg ball is thrown from the top of a 4-m tall building (point A) with a speed of 1 m/s at an angle 2 degrees above the horizontal. If air resistance is negligible, what is the value of the kinetic energy of the ball as it hits the ground?

Answer:
Explanation:
From the question we are told that:
Mass
Height
Speed
Angle
Generally the equation for K.E is mathematically given by
Since
The potential energy and kinetic energy is equal to the kinetic energy as it hits the ground.
Therefore
