- A physics student of mass 43.0 kg is standing at the edge of theflat roof of a building, 12.0 m above the sidewalk. An unfriendly dog isrunning across the roof toward her. Next to her is a large wheel mountedon a horizontal axle at its center. The wheel, used to lift objects from theground to the roof, has a light crank attached to it and a light rope wrappedaround it; the free end of the rope hangs over the edge of the roof. Thestudent grabs the end of the rope and steps off the roof. If the wheel hasradius 0.300 m and a moment of inertia of 9.60 kg . m2 for rotation aboutthe axle, how long does it take her to reach the sidewalk, and how fast willshe be moving just before she lands? Ignore friction in the axle.A 3.00 kg low friction cart sits on a horizontal surface. At each end, there is a spring of force constant 100 N/m attached to a firm support. The cart starts at rest at the equilibrium position. A quick blow of a hammer delivers an impulse of 0.50 N-s to the cart. (a)How long will it take for the cart to return to the equilibrium position? (b) How much energy is delivered to the cart by the impulse of the hammer? (c) How far will the cart travel before returning to the equilibrium position?modified book exercise: Vector Mechanics for Engineers: Statics and Dynamics (8th Edition) chapter 4 and exercise 12 Four boxes are placed on a 17,7 kg uniform wooden plank that rests on two trestles.

- A 0.150 kg frame, when suspended from a coil spring, stretches the spring 0.0400 m. A 0.200 kg lump of putty is dropped from rest onto the frame from a height of 30.0 cm (Fig.). Find the maximum distance the frame moves downward from its initial equilibrium position.For a technology project, a student has built a vehicle, of total mass 6.00 kg, that moves itself. As shown, it runs on four light wheels. A reel is attached to one of the axles, and a cord originally wound on the reel goes up over a pulley attached to the vehicle to support an elevated load. After the vehicle is released from rest, the load descends very slowly, unwinding the cord to turn the axle and make the vehicle move forward (to the left as shown). Friction is negligible in the pulley and axle bearings. The wheels do not slip on the floor. The reel has been constructed with a conical shape so that the load descends at a constant low speed while the vehicle moves horizontally across the floor with constant acceleration, reaching a final velocity of 3.00î m/s. (a) Does the floor impart impulse to the vehicle? If so, how much? (b) Does the floor do work on the vehicle? If so, how much? (c) Does it make sense to say that the final momentum of the vehicle came from the floor? If…Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. A pulley assembly is designed to measure the weight of block F using a counterweight. Springs G and H (k = 960 N/m) are compressed by 0.2 meters. Knowing that the system is in equilibrium, determine the mass of block F. Also, determine the tension carried by cable AI and the forces from bar A and bar C. Notes!There's a single cable from point J to point B. This cable is not attached to the cable from C to F. This cable is also not attached to the horizontal bar at C. There's also a single cable running from A to block M. This cable is not attached to the horizontal bar at A. L is also a block with mass 41 kg.
- 12- A simple pendulum was formed by hanging the mass m from point A with a 6 (m) long rope. pendulum released from horizontal position. Below point A is a nail at distance d. When the rope hits the nail and reaches point B, what is the minimum distance d to keep the rope taut?The 13-kg sphere C is released from rest when θ = 0∘ and the tension in the spring is F = 100 N. The figure shows rod AB hinged at point A. Sphere C is attached to the other end of the rod, labeled as B. Point D is located on the rod, 0.3 meters from point A and 0.15 meters from the center of the sphere. A spring with stiffness k of 500 newtons per meter is attached to the rod at point D by one of its ends. Another end of the spring is fixed at point E, located 0.4 directly above point A. The sphere is shown to be below and to the right of point A. An acute angle between the rod and the horizontal is labeled as theta. Determine the speed of the sphere at the instant θ = 90∘ . Neglect the mass of rod AB and the size of the sphere.Three masses, m, =3 kg, m2 = 5.5 kg, and m3 = 2 kg, are attached to springs, k1 = 50 N/m, k2 = 35 N/m, k3 = 25 N/m, and k4 = 20 N/m, as shown below. Initially the masses are positioned such that the springs are in their natural length (not stretched or compressed); then the masses are slowly released and move downward to an equilibrium position as shown. The equilibrium equations of the three masses are:
- Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. The mechanism shows two identical 2-kg bars that are 0.15 m long each. They are hinged together at the lower ends and are supported at the upper ends by small rollers of negligible mass which roll on a horizontal rail. Determine the steady state angle θ assumed by the bars when they are accelerating under the action of a constant horizontal force 375.90 Newtons. Also, find the forces on the rollers at A and B as well as the reactions at the hinge C.The 11.5 kg slender rod pivoted about point O is pressed against a spring at point A, in which the spring (k = 375 kN/m) is compressed by 27 mm, as shown in Figure Q2(b). At this instance, the rod is at horizontal position and is stationary. If the rod is released from this position, (i) By using the principle of conservation of energy, explain with calculations on how changing the mass of the rod would influence the downward reaction of the pivot when the rod passes through a vertical position.The 11.5 kg slender rod pivoted about point O is pressed against a spring at point A, in which the spring (k = 375 kN/m) is compressed by 27 mm, as shown in Figure Q2(b).
