Question

40 n, -40 n
10 kg
80 kg
an 80 kg person stands on a skateboard and throws a 10 kg ball to the right with 40 n of force.
what direction will the person accelerate?
to the right (+)
to the left (-)
downward
upward

Explanation:

According to Newton's Third Law, when the person exerts a 40 N force to the right on the ball, the ball exerts an equal and opposite (40 N) force on the person. This opposite force acts to the left on the person, causing the person to accelerate in the direction of this force (to the left).

Answer:

to the left (-)
