Q1. A projectile is fired from the top of a vertical cliff at 25.5m/s at an angle of 32 below the horizontal, and strikes water at the same level as the base of the cliff 1.60 seconds later. (Use g = 9.81, and avoid air resistance.)

How far does the projectile land from the base of cliff?

Q2. A block M1 of mass 16.50 kg sits on top of a larger block M2 of mass 26.50 kg which sits on a flat surface. The kinetic friction coefficient between upper and lower block is 0.405. The kinetic friction coefficient between the lower block and the flat surface is 0.105. A horizontal force F = 95N pushes against the upper block, causing it to slide. The friction force between the blocks then causes lower block to slide also. Find out the magnitude of the acceleration of the upper block. Find out the magnitude of the acceleration of the lower block.
