Question: A pendulum is pulled sideways to an angle of E) = 11.4. At this point, the magnitude of the restoring force is 20.2 N. Calculate

A pendulum is pulled sideways to an angle of E) = 11.4\". At this point, the magnitude of the restoring force is 20.2 N. Calculate the mass of the pendulum in KILOGRAHS. Round your answer to one decimal place. A 21.0 kg mass, attached to a spring, is oscillating on a horizontal, frictionless surface. The amplitude of the oscillation is 29.5 cm. If the maximum speed of the mass is 4.7 mfs, calculate the spring constant of the spring. Answer in units of Wm. Express your answer to 3 signicant gures. You can enter answers using scientific notation as per the following example. If your answer is 1.23 x 104, you would enter 1.23E4 in the answer box
