Q1. Blocks A and B are moving toward each other. A has a mass ma =2.0 kg and a velocity Va- 50 î m/s, while B has a mass mB=4.0 kg and a velocity, VBi = - 25 î m/s. After the collision block A is moving with velocity, Vat =30 î m/s and block B is moving with VBf. Use the given symbols throughout the problem. a. Write algebraic equation for initial and final momentums as pi and pf respectively by choosing the direction î and given symbols b. Write algebraic equation for momentum conservation by choosing the direction î and given symbols? c. Solve it for unknown final velocity of block B, VBfafter the collision? What will be the direction?
