Question

When an athlete takes part in a long jump he runs for a while and then jumps. This is because:

• A. inertia of motion helps him to take a longer jump.
• B. running for a time makes him alert.
• C. it helps him to focus on the point of jump.
• D. he can apply more force for the jump after running.

Answer 1

The correct option is A inertia of motion helps him to take a longer jump.

The inertia helps him to retain his horizontal speed and hence the athlete can jump with a greater horizontal velocity to cover a longer distance.
