A 7.3 kg bowling ball is thrown down the alley at a speed of 7.6 m/s before making contact with a 1.4 kg bowling pin. After the collision, the bowling pin gains a forward velocity of 10 m/s as it flies down the pin deck. The ball is also still in motion. What is the total momentum of the system?

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

What are similarities and differences between refraction, reflection, diffraction and absorption?
