A boy has filled his toy box with all his favorite toys and it trying to drag it across the floor. The toy box has a mass of 35 kg (including the toys) and the child pulls with a force of 24 N at an angle of 30 degrees above horizontal (he is pulling mostly horizontally, but some of the force is pulling up). What is the horizontal acceleration of the box if friction is negligible (too small to make a noticeable difference)?

a slab of mass m1 40 kg rests on a frictionless floor, and a block of mass m2 10 kg rests on top of the slab. Between block and slab, the coefficient of static friction is 0.60, and the coefficient of kinetic friction is 0.40.A horizontal force of magnitude 100 N begins to pull directly on the block, as shown. In unit-vector notation, what are the resulting accelerations of (a) the block and (b) the slab?

Three people pull simultaneously on a stubborn donkey. Jack pulls eastward with a force of 94.5 N,94.5 N, Jill pulls with 88.1 N88.1 N in the northeast direction, and Jane pulls to the southeast with 181 N.181 N. (Since the donkey is involved with such uncoordinated people, who can blame it for being stubborn?) Find the magnitude of the net force the people exert on the donkey. What is the direction of the net force? Express this as the angle from the east direction between 0°0° and 90°,90°, with a positive sign for north of east and a negative sign for south of east.
