A person slaps her leg with her hand, which results in her hand coming to rest in a time interval of 2.55 ms from an initial speed of 2.25 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 1.75 kg? magnitude: N Would the contact force on the same hand be any different if the woman clapped her hands together, each with an initial speed of 2.25 m/s, if they come to rest in the same time interval of 2.55 ms? It depends on the coeffcient of friction between the two hands. no, because the second hand has zero momentum no, because the change in momentum for the first hand will be the same yes, because the change in momentum is different yes, because the initial momentum of the system will be different due to the second hand
