An 80-kg parachutist approaches the ground at 5.0 m/s. As she hits the ground, she decelerates at a constant rate over a distance of 1.0 m while her legs buckle under her. What is the force the ground exerts on her feet during the deceleration?

A parachutist whose mass 85 kg drops from a helicopter hovering 2500 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b1=30 N-sec/m when the chute is closed and b2=100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 20 m/sec, after how many seconds...

A BMW of mass 2000 kg is traveling at 42 m/s. It approaches a 1000 kg Volkswagen going 25 m/s in the same direction and strikes it in the rear. Neither driver applies the brakes. Ignore the relatively small force on the cars due to the road and due to air resistance. (a) If the collision slows the BMW down to 33 m/s, what is the speed of the VW after the collision? (b) During the collision, which car exerts...

A baseball approaches home plate at a speed of 47.0 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 52.0 m/s straight up. The ball has a mass of 145 g and is in contact with the bat for 1.80 ms. What is the average vector force the ball exerts on the bat during their interaction?

A 5.0 kg box slides down a 5.0 m high frictionless hill, starting from rest, across a 2.0 m wide horizontal surface, then hits a horizontal spring with spring constant 500 N/m. The ground under the spring is frictionless, but the 2.0 m wide horizontal surface is rough with a coefficient of kinetic friction of 0.25. a. What is the speed of the box just before reaching the rough surface? b. What is the speed of the box just before...

A baseball approaches home plate at a speed of 38.6 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 49 m/s straight up. The ball has a mass of 164 g and is in contact with the bat for 1.55 cs. What is the average force the ball exerts on the bat during their interaction? F =  N i and  N j.
