Without further ado, your extra credit questions:Q1) A shopper pushes a 15 {kg} grocery cart for 25 {m} with a constant, horizontal applied force of 85 {N). If the cart was originally at rest, and there is a kinetic friction coefficient of 0.35felt at the wheels, what is the final velocity of the cart?Q2) A 450 (g) mass is attached to a vertical spring, causing it to stretch 5.0 {cm) from its resting length. If that 450 {g) mass were then removed, and replaced with a 550 (g) mass, whatwould be the change in gravitational potential energy - from the time the mass was initially attached at the spring's resting length, to the time the system finally reached equilibrium?PreviousovoCe4.5789.
