A 85.0 N grocery cart is pushed 13.0 m along an aisle by a shopper who exerts a constant horizontal force of 40.0 N. If all frictional forces are neglected and the cart starts from rest, what is the grocery cart's final speed

2 answers

The mass of the cart is M = W/g = 8.67 kg

The cart acquires kinetic energy equal to the work done on it.

(M/2) V^2 = F * X = 40 * 13 joules

Use mass M and the formula above to calculate V.
well ya see, i wish i could help ya. i need help on my semester exam review and i can't fing anything on it. i have to have it done by tomorrow.
