Question

which soccer ball(s) experienced the strongest force? how do you know?
a all three soccer balls experienced the same force because they changed speed by the same amount.
b the orange soccer ball; it has more mass and the fastest ending speed.
c the blue soccer ball; it takes a stronger force to slow down a more massive object than to speed it up.
d the blue and orange soccer balls; they have more mass than the black soccer ball, but changed speed by the same amount.

Explanation:

According to Newton's second - law of motion $F = ma$ (force equals mass times acceleration). If the change in speed (acceleration) is the same, the object with greater mass will experience a greater force. The blue and orange soccer balls have more mass than the black soccer ball and changed speed by the same amount, so they experience a greater force.

Answer:

D. The blue and orange soccer balls; they have more mass than the black soccer ball, but changed speed by the same amount.
