A juggler throws two balls to the same height so that one is at the halfway point going up when the other is at the halfway point coming down. At that point:
a. Their velocities and accelerations are equal.
b. Their velocities are equal but their accelerations are equal and opposite. c. Their accelerations are equal but their velocities are equal and opposite. d. Their velocities and accelerations are both equal and opposite. e. Their velocities are equal to their accelerations.
Question 2
A boy on a skate board skates off a horizontal bench at a velocity of 10 m/s. One tenth of a second after he leaves the bench, to two significant figures, the magnitudes of his velocity and acceleration are:
a. 10 m/s; 9.8 m/s2.
b. 9.0 m/s; 9.8 m/s2.
c. 9.0 m/s; 9.0 m/s2.
d. 1.0 m/s; 9.0 m/s2.
e. 1.0 m/s; 9.8 m/s2.
