Front

A rocket started at rest. After initiating the launch, it had an acceleration of 90 m/s². How long did it take to reach a speed of 2430 m/s?

Back

27 s

Front

Acceleration in the opposite direction of motion means that your object is:
- constant
- speeding up
- at rest
- slowing down

Back

slowing down
