**drwls**, Sunday, January 13, 2013 at 11:30amAfter the turtle jumps on, conservation of momentum tells you that the velocity of both (V) is

200*0.4 = (200 +3.6)V

V = 0.393 m/s

To slow down the turtle to 0.2 m/s by shooting the skateboard forward, the skateboard achieves velocity v given by

203.6*0.393 = 200*0.2 + 3.6 v

3.6 v= 80.0 -40.0 = 40.0

v = 11.1 m/s
