On the planet Flinx a glorbot is the centerpiece for a common game. This object is dropped from a height of 4.2 m and reaches the ground in 0.34 seconds. Assuming air resistance is negligible, this will be the magnitude of the gravity on Flinx.
What is 73 m/s/s?

A car is driving at some unknown velocity. Suddenly an opossum walks into the road 12 meters in front of the car. The driver instantaneously hits the breaks slowing at a rate of 1.8 m/s/s for 1.2 seconds. This was the final velocity by the time the driver reached the opossum.

A rocket is fired vertically into the air with an acceleration of +40.0 m/s/s. This lasts only 0.2 seconds as there is a problem with the fuel release. At a time 1.3 seconds after the initial launch (and after the rocket reaches the apex), the rocket re-initiates causing a return to the acceleration of +40.0 m/s/s.
