which of these is an example of acceleration?\n a bicyclist turning around a corner\n a car parked in a driveway\n a bus traveling north at 25m/s\n a helicopter waiting to take off

Answer

Explanation:

Step1: Recall acceleration definition

Acceleration is a change in velocity (speed or direction).

Step2: Analyze each option

  • A bicyclist turning around a corner changes direction, so has acceleration.
  • A car parked in a driveway has zero velocity change.
  • A bus traveling north at 25m/s has constant speed and direction (no acceleration if no change).
  • A helicopter waiting to take - off has zero velocity change.

Answer:

a bicyclist turning around a corner
