7. The cart of mass 10 kg moves without frictional loss on a level table. A 10 2 poi N force pulls on the cart horizontally to the right. At the same time, a 30 N
force at an angle of 60° above the horizontal pulls on the cart to the left.
What is the magnitude of the horizontal acceleration of the cart?
