Question

Q2f)

Part F

The figure shows two trajectories, made by two balls launched with different angles and possibly different initial speeds.

Based on the figure, for which trajectory was the ball in the air for the greatest amount of time?

The figure shows two trajectories, made by two balls launched with different angles and possibly different initial speeds.

The balls are in the air for the   same amount of time.

Explanation / Answer

Maximum height = (u sin theta )^2 / 2g


for the first one we can see it has higher Height

therefore higher Usin theta value time of flight = 2u sin theta /g

so whichever body has maximum height will have more time of flight

so the answer is trajectory A
