Question

A 63.0 kgkg parachutist falling vertically at a speed of 6.50 m/sm/s hits the ground, which brings him to a complete stop in a distance of 0.87 mm (roughly half of his height).

1) Assuming constant acceleration after his feet first touch the ground, what is the average force exerted on the parachutist by the ground?

Express your answer with the appropriate units.

Step 1: Given information

Write the given values to the specified variables.

table row m equals cell 63.0 space kg end cell row u equals cell 6.50 space straight m divided by straight s end cell row v equals cell 0 space straight m divided by straight s end cell row h equals cell 0.87 space straight m end cell end table

Here, m, u, v,  are the mass, initial speed, final speed, and height.
