It is more difficult to start moving a heavy carton from rest than it is to keep pushing it with constant velocity. This is because: a. the normal force (N) is greater when the carton is at rest.
b. the coefficient of static friction is less than the coefficient of kinetic friction.
c. initially, the normal force (N) is not perpendicular to the applied force.
d. the coefficient of static friction is greater than the coefficient of kinetic friction.

At 20∘c, the hole in an aluminum ring is 2.800 cm in diameter. you need to slip this ring over a steel shaft that has a room-temperature diameter of 2.804 cm . 1. to what common temperature should the ring and the shaft be heated so that the ring will just fit onto the shaft? coefficients of linear thermal expansion of steel and aluminum are 12×10−6 k−1 and23×10−6 k−1 respectively.
