Santa Clause is about to distribute his gifts, but his reindeer Rudolph is still sleepy. So, instead of flying they use the ground and cross a 20-m-long bridge. Starting from rest, Rudolph pulls Santa and his sleigh, with a force F 30° above the horizontal against a frictional force of 80N. 1. Draw an appropriate free body diagram to represent all the forces acting on Santa and his sleigh. 2. Suppose the combined mass of Santa, his sleigh, and his gifts is 500kg. What is the magnitude of Fif the acceleration of Santa and his sleigh is 1.5 meters per second squared? 3. How much work is done by Rudolph in pulling Santa and his sleigh in crossing the bridge? 4. What is the change in the kinetic energy of Santa and his sleigh after crossing the bridge? 5. How fast are they moving at the end of the bridge?

A 500N block is resting on an inclined plane and is subjected to a constant force of 600N acting parallel to the inclined plane. After the block has moved 3m from rest along the inclined plane, the force 600N is removed. The inclined plane has a slope of 3 vertical to 4 horizontal. Coefficient of friction is 0.20. Solve for the velocity of the block, in m/s, when the force 600N was removed. Round your answer to 2 decimal places.
