Aperson slaps her leg with her hand, which results in her hand coming to rest in a time interval of 2.35 ms from an initial speed of 3.75 m/s . what is the magnitude of the average contact force exerted on the leg, assuming the total mass of the hand and the forearm to be 1.55 kg ?

0.55x745.7j and a calculator

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
