A bronze statue of Buddha was completed in Tokyo in 1993. The statue is 35 m tall and has a mass of 1.00x10^6kg
a. What is the magnitude of the impulse that must act on the statue in order for the velocity to
increase from 0 m/s to 0.20 m s?
b. If the magnitude of the net foree acting on the statue is 12500 N, how long will it take for the
final velocity to be reached?

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.
