A 2 kg object hangs, at rest, on a 1 m long string attached to the ceiling. A 41 g mass is fired with a speed of 19 m/s at the 2 kg mass and makes a perfectly inelastic collision with the 2 kg mass. The subsequent motion of the stuck-together masses is that of a simple pendulum. What is the amplitude 8max of the motion in degree? Let g = 9.8 m/s². Enter a number with one digit behind the decimal point. Question 2 1 pts A helicopter accelerates upward with a cable of mass 6.4 kg and length 15.2 m attached to a mass of 150 kg hanging vertically below it. If a transverse pulse initiated by wobbling of the mass takes 0.247 seconds to travel the length of the cable, what is the upward acceleration of the helicopter in m/s?? Since the mass of the cable is small compared to the hanging mass, make the approximation that the tension is uniform. Use g = 9.8 m/s².
