Homework Help: Physics

Posted by Sarah on Sunday, January 13, 2008 at 10:22pm.

a 5 kg block with a speed of 3 m/s collides with a 10 kg block that has a speed of 2 m/s in the same direction. After the collision, the 10 kg block is observed to be traveling in the original direction with a speed of 2.5 m/s.
a) what is the speed of the 5 kg block immediately after the collision?
b) By how much does the total kinetic energy of the system of the 2 blocks change because of the collision?
c)suppose, instead, that the 10 kg block ends up with a speed of 4 m/s. what then is the change in total KE?
