In the figure, a force of magnitude 11.2 N is applied to a block of mass m2=D0.8 kg. The force is directed up an incline plane with an angle of 37.6°. The box is connected by a cord to another block of mass m 2.6 kg on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord are negligible. What is the tension in the cord in N?

A 2.50 kg object is moving along the x-axis, in the positive direction, at1 .60 m/s. As it passes through the origin, two forces F1 and F2are applied, both forces only have components in the y-direction (Note: The y-components of either force could be positive or negative). The forces are applied for 3.00 s, after which the object is atx=4.80 m,y=10.8 m.If~F1=15.0ˆjN, what is~F2?
