PLEASE HELP ITS DUE IN THE NEXT 30 MINUTES An archer stands at rest on frictionless ice; his total mass including his bow and quiver of arrows is 60.00 kg. He then fires a 0.030 0-kg arrow at 50.0 m/s at an angle of 30.0° above the horizontal. If it takes 650N of force to break the ice and the arrow leaves the bow in 10ms, does the archer fall into the frozen lake?

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.
