Call the applied force 'A'. (Clever ?)
The forces on the cart are 'A' forward and 15 N backward.
The net force on the art is (A-15) forward.
F = m a
Net forward force = (mass of the cart) x (its forward acceleration)
(A - 15) = (16.5) x (2.31)
A - 15 = 38.115
Add 15 to each side:
<u>A = 53.115 newtons</u>
