Calculate the kinetic energy of the putty wad when 1) it reaches its highest point, 2) the instant when passes the top of the wall, and 3) instant just before it hits the ground?

**drwls**, Sunday, February 20, 2011 at 7:03pm1) At the highest point, V = 0

What does that tell you about the kinetic energy then?

2) When it passes the top of the wall (going dwn), it has K.E. = M g H, where H = 4 m is the maximum height thrown.

3) K.E. = M g (H + h)

where h is the height of the wall.
