The box leaves position x=0 with speed v0. the box is slowed by a constant frictional force until it comes to rest at position x=x1. find ff, the magnitude of the average frictional force that acts on the box. (since you don't know the coefficient of friction, don't include it in your answer.)

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.

(asap) uneven heating of the earth's surface is due primarily to the position of the equator, north pole, sun, or moon?
