- A 1200 kg car is traveling towards a hill at a speed of 25.3 m/s when suddenly the car runs out of gas to what vertical hight in meters is the car able to coast up the hill before coming to a stopA 1000N force accelerates a sports car from 33.0 m/s to 38.0 m/s in the direction of the force. If the distance covered by the sports car is 173 m, calculate the sports car’s mass.Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
