assuming

Raindrops of radius 1 mm and mass 4 mg are falling with a speed of 30 m/s on the head of a bald person. the drops splash on the head and come to rest. assuming equivalently that the drops cover a distance equal to their radii on the head, estimate the force exerted by each drop on the head.

Solution Solve with us 1 2 3 Given, radius of a raindrop, r = 1 mm = 10 - 3 m Mass of a raindrop, m = 4 mg = 4 × 10 - 6 kg Distance covered by the drop on the head, s = 1 mm = 10 - 3 m Initial speed of the drop, u = 30 m s - 1 Final speed of the drop, u = 0 m s - 1. Reveal Step
