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.

Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.
