7. Jamal is rolling along on his 4.0 kg skateboard with a constant speed of 3.0 m/s when he
jumps off the back and continues forward with a velocity of 2.0 m/s relative to the ground. This
causes the skateboard to go flying forward with a speed of 15.5 m/s relative to the ground.
What is Jamal's mass?
