Question
Transcribed Image Text:Which one of the following statements is true about the acceleration of a ball which
has been thrown into the air (Ignore air resistance)
a) The acceleration is always downward
b)
The acceleration at any given instant depends on the angle at which the ball
was thrown
c) The acceleration is least when the ball reaches the top of its flight
d) The acceleration always has the same direction as the ball's velocity.
Expert Solution
Step 1
When a ball is thrown vertically upwards the only thing acting on it is the acceleration due to gravity which is acting in the downward direction. The velocity is acting in the upward direction, the velocity of the ball goes on decreasing and it finally becomes zero at the maximum height due to the downward acceleration, and from that point, it starts to fall freely under gravity.
