Problem Statement A bullet is moving at a speed of 350 m/s when it embeds into a lump of moist clay. The bullet penetrates for a distance of 0.05 m. Determine the acceleration of the bullet while moving into the clay. (Assume a uniform acceleration.) Solution to physics problem Initial velocity of the bullet U=350 […]

## Solution to problems – class 9 – Set 1 Q 29

Problem Statement A plane has a takeoff speed of 100 m/s and requires 1500 m to reach that speed. Determine the acceleration of the plane and the time required to reach this speed. Solution It starts from rest. So initial velocity U = 0 Final velocity = take off velocity = V = 100 m/s […]
