Physics

Answer all parts. Write big, clear and legibly.  

A 0.10kg dart is fired horizontally at the center of a 0.80kgvertically hanging block, sticking to it. The system reaches amaximum height, h, of 0.20m above the collision point.

Find:

a) the velocity of the dart – block system just after thecollision

b) the velocity of the dart before collision

c) the energy lost during the collision.

d) if the dart gains its speed due to a spring system that isinitially compressed 0.05m from its equilibrium

position, determine the spring constant.

e) If the dart didn’t stick to

the block, but instead fell vertically after collision, wouldthe initial velocity of the

dart have to be greater, less than, or equal to the velocitythat was found in part (b)? Justify.
