a rescue helicopter is moving directly upward at a constant speed. which statement describes the helicopters motion? the helicopter has a constant velocity. the helicopter is accelerating.
Answer
Explanation:
Step1: Recall velocity - acceleration relationship
Velocity is a vector quantity with speed and direction. Acceleration is the rate of change of velocity.
Step2: Analyze the helicopter's motion
The helicopter is moving directly upward at a constant speed. Since speed is constant and direction is not changing (always upward), the velocity is constant. If velocity is constant, the rate of change of velocity (acceleration) is 0.
Answer:
The helicopter has a constant velocity.
