Which object is not accelerating?

A A baseball player sliding into home base.

B A blue Ford 150 pick-up truck speeding up from 50 mph to 80 mph.

C A ladybug crawling forward at constant rate of 2.5 m/s.

D A student riding on a Ferris wheel at a constant rate of 5.0 m/s.

C. The ladybug's speed and direction are not changing, so she has no acceleration.

In A, B, and D, either speed or direction are changing, and that's acceleration.
