Question

boy pulls a toy cart of mass 2 kg with a force of 3 N at an angle of 60° with respect to the horizontal road. What is the acceleration produced by the cart?

Well, break the force pulling into a horizontal component, and a vertical component.

Horizontal: 3cos60=1.5N

It bothers me that friction is being ignored, however..

Pullingforce-friction=m*a
1.5-0=2*acceleration solve for acceleration.
