1. The problem statement, all variables and given/known data A grocery cart is being pushed with a force of 450 N at an angle of 30 degrees to the horizontal. If the mass of the cart and the groceries is 42 kg: a) Find force of friction if coefficient of friction is 0.6 b) Find acceleration of cart. 2. Relevant equations Ff=uFnormal F=ma Fn=mg 3. The attempt at a solution I figured out part A and I got 3.8 X 10^2 N as force of friction. For part B, I tried to find force applied. Fa = 450 N X cos30 degrees = 389.7 N and then find net force: Fnet = 389.7 - (3.8 X 10^2) = 9.7 and then find acceleration: a = 9.7 / 42 = 0.23 But the answer is wrong and I checked from my book. Can someone tell me if I am right on part B of this question. Thanks.
