31. A cyclist has just finished a race. At the finish line they were travelling at 14m/s, and began to subject themselves to an acceleration of -1.8m/s/s a) what is the cyclist's velocity 4 seconds after the race had completed? b) how far will they have travelled by the time of their stop? 32/ During a vertical jump a subject with a mass of 75 kg produced an impulse of 150Ns a) What is the initial take off velocity? b) How much time did it take for them to reach the apex? c) What then, was the jump height? 31.
