Question: The spring stiffness is k = 15 Nm. The spring in Figure Q6 is unstretched when s=0 m. The 7 kg cart is moved

The spring stiffness is k = 15 Nm. The spring in Figure

The spring stiffness is k = 15 Nm. The spring in Figure Q6 is unstretched when s=0 m. The 7 kg cart is moved to position s= -1.6 m and released from rest. What is the magnitude of the velocity (in m s) when the cart is in position s = 0 m? Provide only the numerical value and do not include the units in the answer box. Provide your answer to three significant figures. Linn Figure Q6: Cart pulling a spring. 20
