question 32

Multiple Choice

A toy rocket is launched vertically from ground level at time t = 0.00 s. The rocket engine provides constant upward acceleration during the burn phase.

The time interval during which the rocket engine provided the upward acceleration, is closest to

• A)2.1 s.
• B)2.3 s.
• C)1.9 s.
• D)1.7 s.
• E)1.5 s.
