This time the pendulum is 1.17 m long Suppose you start with the pendulum hanging vertically, at rest. You then give it a push so that it starts swinging with a speed of 2.00 m/s. What maximum angle (in degrees) will it reach, with respect to the vertical, before falling back down? O 13.7 degrees 51.5 degrees O 42.9 degrees 34.3 degrees QUESTION5 This time, the pendulum is 1.80 m long and has a mass of 4.42 kg. You give it a push away from vertical so that it starts swinging with a speed of 1.83 m/s. Due to friction at the pivot point, 1.00 Joule of the pendulums initial kinetic energy is lost as heat during the upward swing. What maximum angle will it reach, with respect to the vertical, before falling back down? O 23.4 degrees 25.2 degrees 42.1 degrees 33.7 degrees QUESTION 6 You are sitting in a sled, at rest on a pond covered with nice, thick, frictionless ice. Your own mass is 93.7 kg, and the mass of the sled when empty is 10.0 kg. From shore, someone throws a baseball of mass 0.145 kg to you, and you catch it; the horizontal component of the ball s velocity is 28.6 m/s. What will be the sled s (and your) speed with respect to the surface of the pond after you catch the ball? O 3.99 cm/s 4.42 cm/s 40.9 cm/s 2 00 cm/s
