Question

The man jumps from the window of a burning hotel and lands in a safety net that stops him fall in 1 mm. Determine the average force that the net exerts on the man if he enters the net at a speed of 28 m/sm/s. Assume that the man's mass is 64 kgkg.

Answer 1

Answer:

Explanation:

Given that,

time =1minute=60seconds

Speed=28m/s

Mass of man=64kg.

Then, Force?

Force is given as

F=ma

Where a is given as v/t

Then,

F=mv/t

F=64×28/60

F=29.87N.

The average force exerted on the man is 29.87N
