Theywish to just reach the surface of the river, when A, attachedto the cord, lets go of B at the instant they touch the water.Determine the proper unstretched length of the cord to dothe stunt, and calculate the maximum acceleration ofstudent A and the maximum height he reaches above thewater after the rebound. From your results, comment onthe feasibility of doing this stunt.120 ftProb. 14-86

Q5: The 10 kN body A shown in Fig. (6) slides on inclined plane. Determine the weight of body B if its velocity changes from 2m/sec upward to 9m/sec upward while it moves 12m. (20 points)
The 65-kg crate is stationary when the force P is applied. Determine the resulting acceleration of the crate if (a) P = 0, (b) P = 223 N, and (c) P = 488 N. The acceleration is positive if up the slope, negative if down the slope. P Part 1 P 65 kg. Incorrect Part (o). We need to decide if the block moves. The easy way to make this decision is to assume that the block does not move and then to test this assumption. If P = 0, what friction force F is needed to keep the block from moving? 4₂ mg Answer: F = 1 260 [#₂ = 0.27 HA=0.20 N N

Pr4. Two bodies are launched at the same time from two points A and B located at the same height. The distance between points A and B is d. One of the bodies starts from point A upwards with speed v1, while the other starts from point B towards point A with initial speed v2. What will be the minimal distance between the bodies during their motion? (The gravitational acceleration is g, neglect the air drag. The bodies do not reach the ground before the moment of the minimal distance.)
