It was once recorded that a Jaguar left skid marks that were 290 m in length. Assuming that the Jaguar skidded to a stop with a constant acceleration of -3.90 m/s2, determine the speed of the Jaguar before it began to skid

• vi = 47.6 m/s

• vi = 625 m/s

• vi = 2.67 m/s

• vi = 7.88 m/s

A feather is dropped on the moon from a height of 1.40 meters. The acceleration of gravity on the moon is 1.67 m/s2. Determine the time for the feather to fall to the surface of the moon.

• t = 1.72 s

• t = 2.55 s

• t = 2.22 s

• t = 1.29 s
