Answer:

Explanation:
given,
mass of boy(m₁) = 40 kg
mass of the skateboard(m₂) = 2.50 kg
velocity of skateboard(V) = 5.30 m/s
speed of the boy(v₁) = 6 m/s at 9.50° above the horizontal
friction force is not acting in x-direction hence no we can apply conservation of momentum in x- direction
as the boy jumps over sidewalk skateboard cannot go through the sidewalk, there must be some force in the y direction so, momentum is not conserved.







negative sign represent velocity of the skateboard is in the opposite direction of boy.
