A 25kg chair initially at rest on a horizontal floor requires a 165 n horizontal force to set it in motion. Once the chair is in motion , a 1227 n horizntal force keeps it moving at a constant velocity. a. find the coefficient of static friction between the chair and the floor.
b. find the coefficient of kinetic friction between the chair and the fllor

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
