At the local grocery store, you push a 13.9 kg shopping cart. You stop for a moment to add a bag of dog food to your cart. With a force of 12.0 N, you accelerate the cart from rest through a distance of 2.00 m in 3.00 s. What was the mass of the dog food?

1. Is the cart frictionless?

If so, compute the acceleration a and use
F = m a
to solve for the mass m.

Hint: X = 2.00 m = (1/2) a t^2
