- Starting from a standstill, Abi (mass = 55.00 kg) performs a vertical jump. a.) How much does Abi weigh (in Newtons)?QUESTION 19 A 5.0-kg object is executing simple harmonic motion, while attached to a spring that obeys Hooke's law, according the the graph below. What is the value of the spring constant? x (m) t (s) 1In the image is a stopper attached to a fishing line that is threaded theough a glass rod. Hanging from the end of the line opposite the stopper is a 100-gram mass. The stopper is being whirled in a horizontal circle, first quickly, then decreasing to a slower speed. a. Is the string pulling inward on the stopper? b. Is there a force pulling the stopper outward? c. True or false: The inward force and outward forces balance, and since the speed is constant, there's no acceleration and there is equilibrium.
