You push a box of mass 20.6 kg with your car up to an icy hill slope of irregular shape to a height 4.3 m. The box has a speed 12.3 m/s when it starts up the hill, the same time that you brake. It then rises up to the top (withno friction) to a flat area before sliding into a box larger box of mass 19 kg. The boxes then fall off a sheer cliff together to the ground (with no drag).What is the velocity of the pair just before hitting the ground? { Vector Form }2)

Write the given data with suitable variables. m1=20.6 kgm2=19 kgh=4.3 m

To apply Newton’s second law and the theorem of conservation of energy to solve kinetic problems. A bungee jumper wants to jump off the edge of a bridge that spans a river below. The jumper has a mass m, and the surface of the bridge is a height h above the water. The bungee cord, which has lengthL when unstretched, will first straighten and then stretch as the jumper falls.Assume the following: The bungee cord behaves as an ideal spring once it begins to stretch and has spring constant k. The jumper does not actually jump but simply steps off the edge of the bridge and falls straight downward. The jumper's height is negligible compared to the length of the bungee cord. Thus, the jumper can be treated as a point particle. Use g for the magnitude of the acceleration due to gravity. How far below the bridge, d, will the jumper eventually be hanging, once the jumper stops oscillating and comes finally to rest? Assume that the jumper does not touch the water. Express your answer in…
A 5-kg bag is gently pushed off the top of a wall and swings in a vertical plane at the end of a 2.4- m rope which can withstand a maximum tension Fm. For Fm from 40 to 140 N use computational software to determine (a) the difference in elevation h between point A and point B where the rope will break, (b) the distance d from the vertical wall to the point where the bag will strike the floor. -2.4m A 3m B'

Q3/ A 10 Kg block slides down a hill that is 200 cm tall as shown in the figure with initial speed of 12 m/s: (a) what is the speed of the block when it reaches the bottom of the hill at position B assuming no friction? (b) what is the final speed of the block at position B after traveling a total distance of 500 cm, assuming no friction?
: A pilot in a fast jet aircraft loops the loop. The radius of the loop is 400 m, and the aircraft has a speed of 150 m/s when it passes through the bottom of the loop. What is the apparent weight that the pilot feels; in other words, what is the force with which she presses against her chair? Express the answer as a multiple of her normal weight
4) A 1.6-lb collar is attached to a spring and slides without friction along a circular rod in a vertical plane. The spring has an unstretched length of 6 in. The collar is released from being held at A, and it passes ponit B with a speed of 16.0 ft/s. Determine the spring constant. The circular rod is kept from moving.

A block of weight 800N rests on a rough horizontal surface of coefficient of friction 0.2. It is pulled by a force of 1000N applied at an angle of 300 to the horizontal. Determine the velocity attained by the block after it has moved 30 m starting from rest. Proceed to calculate the further distance moved by the body if the pull is removed.
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? (Round your answer to at least three significant figures.) m/s (c) Assuming that the sprinter's speed increases at a…
Jumping up before the elevator hits. After the cable snaps and the safety system fails, an elevator cab free-falls from a height of 34 m. During the collision at the bottom of the elevator shaft, a 90 kg passenger is stopped in 6.0 ms. (Assume that neither the passenger nor the cab rebounds.) (a) What is the magnitude of the impulse on the passenger during the collision? N's (b) What is the magnitude of the average force on the passenger during the collision? N Suppose the passenger were to jump upward with a speed of 6.5 m/s relative to the cab floor just before the cab hits the bottom of the shaft. Assume the same stopping time as above. (c) What is the magnitude of the impulse on the passenger during the collision? N•s (d) What is the magnitude of the average force on the passenger during the collision? N
A skier on a 25° slope and his mass is 80 kg. If his constant velocity and the coefficient of kinetic friction between the ski and the snow is 9m/sand 0.80, respectively, compute his velocity when he has skid 20m from his initialposition and a drag force experienced by the skier equivalent to a magnitude of 0.6V^2.
