A 2 kg object hangs, at rest. on a 1 m long string attached to the ceiling. A 62 g mass is red with a speed of 14 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 {3mx of the motion in degree? Let g = 9.8 m/s2. Enter a number with one digit behind the decimal point. A helicopter accelerates upward with a cable of mass 7.7 kg and length 18.3 m attached to a mass of 150 kg hanging vertically below it. If a transverse pulse initiated by wobbling of the mass takes 0.236 seconds to travel the length of the cable, what is the upward acceleration of the helicopter in mIsz? 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/sz. Enter a number with two digits behind the decimal point. Suppose the length of a clock's pendulum is increased by 0.56 %, exactly at noon one day. How many seconds will the clock be off 24.00 hours later, assuming it the pendulum has kept perfect time before the change? Enter a negative integer if the clock displays a time before noon, and a positive integer if the clock displays a time after noon
