1. a 150-g ball is thrown at a stationary 3500-g wood block. after the collision, the velocity of both objects is .85 m/s. what was the initial speed of the ball of dough? a) 2.4 m/s b) 2.7 m/s c) 21 m/s d) 23 m/s 2. why is impulse the same whether an object is stopped by a haystack or a concrete wall? 3. a 240-kg quarterback catches a football while he is stationary. an 80-kg opponent runs toward him at 2 m/s and tackles him. after the collision, the quarterback travels backward at 1 m/s. what is the final velocity of the opponent?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
