With horizontal distance, initial velocity and angles problem?
17. recall that the equation for the horizontal distance h in feet of a projectile with initial velocity v0 and initial angle theta is given by h=v0^2/16 sin theta cos theta.
a. assume the initial velocity is 60 feet/second . what initial angle will you need to ensure that the horizontal distance will be exactly 100 feet?
b. assume the initial velocity is 60 feet/second. what is the maximum horizontal distance possible and at what angle does this occur?

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.
