Question:

A mass of 100 g is projected with an initial velocity of 12 m/s at an angle of 60° with the horizontal. Find the difference between the kinetic energy at the point of projection and the kinetic energy at the highest point.

Show Hint

The kinetic energy at the highest point of projectile motion is due to the horizontal velocity alone.

The Correct Option is B

Solution and Explanation

At the highest point, the vertical component of velocity is zero, and thus the kinetic energy is only due to the horizontal component of velocity. Calculate the initial kinetic energy and the kinetic energy at the highest point and find the difference.
