Concept explainers

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

**Physics Problem: Mark and Martin's Dive**

*Scenario:*

Mark and Martin dive from a bridge into the lake below. Mark simply drops straight down from the edge. Martin takes a running start and jumps with an initial horizontal velocity of 25 m/s. If we can ignore the effects of air resistance,

1. How long does it take for Mark to reach the lake below?
2. How long does it take for Martin to reach the lake below?

*Note:*

- Consider the vertical motion only for calculating the time, as horizontal velocity does not affect the time taken to reach the lake below in the absence of air resistance.

What is the velocity when the car hits the water?
Small-plane pilots regularly compete in “message drop” competitions, dropping heavy weights (for which air resistance can be ignored) from their low-flying planes and scoring points for having the weights land close to a target. A plane 60 m above the ground is flying directly toward a target at 45 m/s. a. At what distance from the target should the pilot drop the weight? b. The pilot looks down at the weight after she drops it. Where is the plane located at the instant the weight hits the ground—not yet over the target, directly over the target, or past the target?
