A force of 1200N acts on a 0.5kg steel ball as a result of a collision lasting 25ms. If the force is in a direction opposite to the initial velocity of 14ms-1, then the final speed of the steel ball would be
Step 1: Given data
Mass of ball, m=0.5kg
Initial velocity, u=14m/s
Step 2: Find final speed of the steel ball
Hence, option D is correct.
