constants Submit Previous Answers A small block on a frictionless, horizontal surface has a mass of 2.90*10-2 kg. It is attached to a massless cord passing through a hole in the surface (Figure 1). The block is originally revolving at a distance of 0.300 m from the hole with an angular speed of 2.25 rad/s. The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.150 m. Model the block as...

A block of weight w = 15.0 N sits on a frictionless inclined plane, which makes an angle @ = 33.0° with respect to the horizontal, as shown in the figure. (Figure 1)A force of magnitude F = 8.17 N, applied parallel to the incline, is just sufficient to pull the block up the plane at constant speed. Review The block moves up an incline with constant speed. What is the total work Wtotal done on the block by all...

The diagram below shows a block of mass m=2.00kg on a frictionless horizontal surface, as seen from above. Three forces of magnitudes F1=4.00N, F2=6.00N, and F3=8.00N are applied to the block, initially at rest on the surface, at angles shown on the diagram. (Figure 1) In this problem, you will determine the resultant (total) force vector from the combination of the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are...
