- As illustrated in the figure, consider a soccer player kicking a stationary ball of mass m = 0.5 kg. Assuming that the air resistance is negligible, the ball undergoes a projectile motion (shown in figure). It is recorded that the angle of release of the ball is 0 = 25.2° and the maximum height reached by the ball is h = 4.5 m. If the time during which the foot of the soccer player remained in contact with the ball is At = determine: (a) The speed of release, V, of the ball 0.12 s, (b) The horizontal distance, I, between the initial position of the ball and the landing point (c) The momentum, p, of the ball at the instant of takeoff (d) The magnitude of force, F, applied on the ball by the soccer player УAt a pool, a 3.26 kg life ring is thrown by a lifeguard to a struggling swimmer. The lifeguard stand is 1.75 m above the water. If air resistance is negligible and the life ring is launch with a speed of 8.23 m/s at the angle indicated in the figure: a) Find the height of the life ring and the net force on the life ring at point P. b) Find how far the life ring lands from the base of the stand. c) With what velocity did the life ring strike the water at point Q? 30°Asap please.....
- A boy of mass m = 36 kg is standing initially at rest relative to the moving walkway, which has a constant horizontal speed u = 1.1 m/s. He decides to accelerate his progress and starts to walk from point A with a steadily increasing speed and reaches point B (a distance s = 29 m) with a speed dx/dt = v = 2.5 m/s relative to the walkway. During his acceleration he generates an average horizontal force F between his shoes and the walkway. Calculate the work done on the boy by the force F from an absolute viewpoint and then from a relative viewpoint. Explain the difference. Answers: Absolute viewpoint, Work = i Relative viewpoint, Work = i JDo 3-7, 3-8 and 3-11 -√3.7 # 3-7 Determine the magnitude and direction angle of force F, so that the particle shown in Fig. P3-7 is in equilib- rium.

What must the minimum muzzle velocity be for the shell to clear the top of the cliff? The ground at the top of the cliff is level, with a constant elevation of 15.0 m above the cannon. Under the conditions of the previous part, how far does the shell land past the edge of the cliff?
- Two crates of fruit are released from the top of a ramp inclined at 30 degrees from the horizontal and 4.5 meter long. The two crates consist of an apple crate of mass 20 kg that is placed in front of a watermelon crate of mass 80 kg. The apple crate has a coefficient of friction of 0.20 while the watermelon crate has a coefficient of friction of 0.15. How long does it take the apple crate to reach the bottom of the incline if it needs to travel a distance of 4.5 meters?A block of mass m = 0.5 kg is kicked so that it slides up a ramp inclined at an angle θ = 30°. At the bottom of the ramp, the block has speed v0 = 4.0 m/s. There is a coefficient of kinetic friction between the block and ramp µK = 0.18. (a) How far up the ramp does the block slide? (b) Assume that the block comes to rest and does not slide back down the ramp. What must be the minimum coefficient of static friction between the block and ramp?Help
