Dragsters are cars that reach high speeds very quickly through massive acceleration. For example, a dragster may zoom from 0 to 480 kph in 4.5 seconds. What is a dragster's average acceleration?

A1000-kg weather rocket is launched straight up. the rocket motor provides a constant acceleration for 16-s, then the motor stops. the rocket altitude 20-s after launch is 510-m. you can ignore any effects of air resistance. a. what was the rocket’s acceleration during the first 16-s? b. what is the rocket’s speed as it passes through a cloud 5100-m above the ground?
