17.
According to Newton’s Third Law, if someone jumps off a skateboard, the skateboard will roll backwards because:
a)
the mass of the skateboard is the same as the mass of the person jumping of it
b)
the pull of gravity on the person is the same as on the skateboard, regardless of size.

the air resistance on the person is great and the friction on the skateboard is small.
d)
for the force that sent the person forward, there is an equal force pushing back on the skateboard.

the people in the car will continue to move in the same direction and at the same speed as before the impact
b)
the speed of the car always increases, giving it greater force since the mass will remain the same
