ANALYSIS: A cyclist bikes at a speed 12 m/s when suddenly he comes to a muddy stretch with an effective coefficient of friction of 0.60. Will the cyclist be able to get out of the muddy stretch without having to pedal if it lasts 10 meters? If that is the case, how fast will he be when he emerges? Give details using the graphic organizer below: Make a claim: Provide evidences: Give their reasons:

A 2.0 kg object is moving to the right with a speed of 1.0 m/s when it experiences the force shown in the figure. What are the object’s speed and direction after the force ends? Express your answer to two significant figures and include the appropriate units. Enter positive value if the speed is directed to the right and negative value if the speed is directed to the left.
pervious question: Same type of track as in the previous problem, this time with d = 4.73 m. The block starts at x = 0, and is given a push to the left with an initial speed of 7.57 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? New question: OK, same sort of track, but now with d = 2.12 m. Now suppose the blocks starts on the track at x = 4.10 m. The block is given a push to the left and begins to slide up the track, eventually reaching its maximum height at x = 0, at which point it turns around and begins sliding down. What was its initial speed in this case? 18.98 m/s 12.47 m/s 8.82 m/s 14.90 m/s

A 4.0 kg block is initially at rest at a height of H=4.0 m on a ramp. The block then slides down a ramp and encounters a region of friction for Z=3.0 m Finally, stickperson pushes on the block for 4.0 m to bring the block to a stop. With what force did stickperson push to bring the block to a stop? no friction on ramp 3m 'Z' meters of friction region of friction uk = 0.21 no friction during push W
Determine the magnitude of the vertical reaction at A if P = 326 N and Q = 1187 N. Let x = 2.55 m, y = 2.5 m, and z = 2.09 m. Round off only on the final answer expressed in 3 decimal places. Instead of units, indicate the direction of the vertical reaction at A : use U if upward, D if downward.
