Answer #1

First, find vertical component of displacement: Find velocity of bullet-block system after the collsion M2 m+ M Here, m and M are mass of bullet and block respectively 28x10-3 kg 28x10 kg +3.1kg 190 m/s 1.70 m/s Height rai sed by bullet and block system (1.70 m/s) 2(9.8 m/s 0.147 m Round off the result to 2 significant figures h-0.15 m To find the horizontal component apply the pythogerous theroem (28m)-(2.8m-0.147 m) 0.897 m x-/( Round off the result to 2 significant figures x 0.90 m
