A 1.5-kg mass has an acceleration of (4.0i ^ − 3.0j ^ ) m/s2. Only two forces act on the mass. If one of the forces is (2.0i ^ − 1.4j ^ ) N, what is the magnitude of the other force?
In the figure here, a box of Cheerios (mass mc = 1.80 kg) and a box of Wheaties (mass mw = 3.40 kg) are accelerated across a
horizontal surface by a horizontal force applied to the Cheerios box. The magnitude of the frictional force on the Cheerios box is 2.20
N, and the magnitude of the frictional force on the Wheaties box is 4.40 N. If the magnitude of
is 12.9 N, what is the
magnitude of the force on the Wheaties box from the Cheerios box?
A 55-kg box rests on a horizontal surface. A force of 300.0 N is pulling the box toward the right horizontal direction and a force of 105.0 N is pulling the box toward the left horizontal direction. What is the magnitude of the box’s acceleration? Ignore friction.
