An arrow is fired with a speed of 20.0 m/s at a block ofStyrofoam resting on a smooth surface. The arrow penetrates acertain distance into the block before coming to rest relative toit. During this process the arrow's deceleration has amagnitude of 1550 m/s^2 and the block's acceleration has amagnitude of 450 m/s^2.

a) how long does it take for the arrow to stop moving withrespect to the block?

b) what is the common speed of the arrow and the block whenthis happens?

c) how far into the block does the arrow penetrate?
