1. A spacecraft travels at 1.5 X 10 m/s relative to Earth. A process onboard the ship as measured by a stationary clock on Earth takes 85 min. How long would the same process take as measured by a clock onboard the ship?(5 marks)1. A 0.30 kg football is thrown from a height of 2.5 m with an initial velocity of 25.0 m/s (34 above the horizontal axis). Assuming that there is no air resistance and that the ball lands on the ground, how far will the ball travel horizontally? (5 marks) 2. A way to test the tensile strength of a wire is to place a mass at the end of it and spin the mass with uniform circular motion. The speed at which the wire breaks is a measure of its strength. The maximum frequency of rotation before a certain wire breaks is 35.5 Hz. The wire is 50.5 cm long and has a mass of 0.656 kg. (a) Determine the speed with which the mass moves. (b) Calculate the centripetal force acting on the wire
