Question

*1. A clay ball has a mass of 2 kg and a velocity of 10 m/s. a) How much momentum does it have? b) The 2 kg ball strikes another ball, which is stationary, head on. The second ball has a mass of 3 kg. The two balls stick together. How much momentum will the combination have after the collision? c) What velocity will the combined masses have after the collision?

Answer 1

3 kg mass of clay ball = m = rng, neloufy - 10m/s (9 momentum of ball ap=mv = 2410 kg-m/s = 20 legums (2+3) kg osioms roms BV =0ms Stick before collision after collision from consennation of momentum, we can say sore initial momentum erfind momentum affer collision 2x10 4340 o final momentum & offer collinan Hence combination have find momentum affer Collinon i 20 kg-m/s O find momentum affes collision = 20 = (2+3) = 20 = v= 20 = 4 mps navi = youps Hence combined mass home velouty ymps affer collision.
