A Block Of Mass M 5 78 Kg Is Attached To A Spring Which Is Resting On A Horizontal Frictionless Table The Block Is P 1 (78.48 KiB) Viewed 29 times
A block of mass m = 5.78 kg is attached to a spring, which is resting on a horizontal frictionless table. The block is pushed into the spring, compressing it by 5.00 cm, and is then released from rest. The spring begins to push the block back toward the equilibrium position at x = 0 cm. The graph shows the component of the force (in Newtons) exerted by the spring on the block versus the position of the block (in centimeters) relative to equilibrium. Use the graph to answer the questions. How much work is done by the spring in pushing the block from its initial position at x = -5.00 cm to x = 2.53 cm? work: 11.2 Incorrect J What is the speed of the block when it reaches x = 2.53 cm? -5 -4 -3 -2 6- 5- 3 2 1- -1 -2 -3 -4 -5 --6- F. (N) 1 2 4 x (cm) 5
work: 11.2 speed: Incorrect What is the speed of the block when it reaches x = 2.53 cm? 1.97 Incorrect What is the maximum speed of the block? maximum speed: 2.28 J Incorrect m/s m/s
