The figure shows a graph of the position
x of two cars, C and D, as a function of time
t.

According to this graph, which statements about these cars must be true? (There could be more than one correct choice.)
◦ The magnitude of the acceleration of car C is less than the magnitude of the acceleration of car D.
◦ Both cars have the same acceleration.
◦ The magnitude of the acceleration of car C is greater than the magnitude of the acceleration of car D.
◦ The cars meet at time
t = 10 s.
◦ At time
t = 10 s, both cars have the same velocity.
