A fireman (mass of 100 kg) jumps on the station’s firepole. The force of gravity pulls him down with 1000 N. A few feet down the pole, he is traveling toward the ground at a constant velocity. The frictional force (exerted by his hands on the pole) opposing the fireman’s weight is?

Answer #1
  • 1000 N.

Note- since speed of fireman is constant, friction force on him by pole is equal to his weight. And equal friction force his fingers exert on the pole.

    A 82 kg person has his center of gravity 1.0 meters above the ground in a standing position (height that person comes off the ground during a jump). During a squat jump, he crouches down so that his centre of gravity is 0.3 meters above the ground. As he jumps, he exerts an average force of 1258 Newtons against the ground. You can think of this average exerted force as the average normal force or average ground reaction force being...

    1. If a sky-diver jumps out of a plane, two forces will act on him, gravity and air resistance. If we assume air resistance is proportional to the velocity, we get the total force on the sky diver will be F = −gm − kv, where g is a acceleration due to gravity on the surface of the earth, m is the mass of the sky-diver, v is the velocity of the sky-diver, and k is constant of proportionality for...
