e= 45 3 m 大 5 m A 60-kg man sprints towards a river, attempting to grasp a 3-m rope connected to a tree. Before grabbing the rope, he sprints at a speed of 5 m/s with a uniform acceleration of 3 m/s² and a distance of 5 m. During his run, he encounters a horizontal air resistance of 10 N. Then, using the 3-m rope, he swings across the river at a constant speed before letting go of the rope. Determine the following: (a) the time he spent running before reaching the rope and the velocity of the man upon grabbing the rope, (b) traction force during running, and the tension in the rope just before letting it go.

A 105 kg guy runs at 3.25 m/s down the parking lot to catch a cart before it hits his car. The cart seems to gain speed as it rolls in the lot causing the guy to change his velocity to 4.5 m/s over a period of 0.77 seconds. What force did the guy use as he changed his velocity

During an Olympic 100-m sprint race, Usain Bolt, the world record holder in that race, quickly accelerates to his top speed of 12.4 m/s. Analysis of his technique has shown that each of his feet make contact with the ground for 0.0800 s, exerting a force of magnitude 2.80 x 10° N during this contact. This allows the 94.0 kg Bolt to leap forward and remain airborne for 0.120 s until the next foot touches the ground. (Ignore air resistance.) (a) What are the magnitudes of the horizontal and vertical components of the force (in N) Bolt's feet exert on the ground? (Round your answers to at least three significant figures.) horizontal N vertical (b) Assuming that the sprinter accelerates at a constant rate while his feet are in contact with the ground and does not slow down when he is airborne, by what amount does Bolt's horizontal speed (in m/s) increase with each step?
