A bullet (W1 = 2.5 oz) with a is fired horizontally with a velocity v1 = 1675 ft/sec into the block (W2 = 6.1 lb) of soft wood initially at rest on the horizontal surface. The bullet emerges from the block with the velocity v2 = 1195 ft/sec, and the block is observed to slide a distance of d = 8.9 ft before coming to rest. Determine the coefficient of kinetic friction μk between the block and the supporting surface.

Aprojectile is launched horizontally 10m above the ground and with an initial velocity of 15 m/s. a) sketch the trajectory using an appropriate coordination system. b) how long for the projectile to reach the ground. c) how far did projectile travel horizontally before striking the ground. d) determine the projectilex & y position at t-1.3s e) determine the magnitude and direction of projectile velocity at t= 1.3s f) determine the magnitude and direction of projectile acceleration at t-1.3s
