Answer:
Answer:
The speed of the kid and the skateboard together is 0.723 m/s
Explanation:
Let the mass of the kid be
Let the mass of the skateboard be
The initial speed of the skateboard,
The initial horizontal speed of the boy as he jumps on the skateboard,
Let the speed of the kid and the skateboard together be v
According to the principle of conservation of momentum:
Substituting the appropriate values into the given equation
36 = 49.8 v
v = 36/49.8
v = 0.723 m/s
