Question:
A 1.50 kg snowball is fired from a cliff I2.5 m high. The snowball's initial velocity is 14.0 m/s, directed 41.0o above the horizontal.
(a) How much work is done on the snowball by the gravitational force during its flight to the flat ground below the cliff?
(b) What is the change in the gravitational potential energy of the snowball-Earth system during the flight?
(c) If that gravitational potential energy is taken to be zero at the height of the cliff what is its value when the snowball reaches the ground?
Step by Step Answer:
a The force of gravity is constant so the work it does is given b...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
