2. A block with a mass of 5.00 kg slides down a surface inclined at 36.9° from horizontal, attached to a string wrapped around a flywheel, as shown in the figure. The flywheel has a mass of 8.50 kg and a radius of 30.0 cm, and rotates freely about its central axis. Assume there is no friction between the block and the surface. [A disk of radius R and mass M has I = MR² about its axis.] OM m 5.00 kg 36.9° a. Find the magnitude of the block's acceleration down the ramp. b. Find the tension in the string. c. Find the angular velocity of the flywheel after the mass has slid 2.00 m down the incline. 7
The crane shown in the figure is lifting a 389-kg crate upward with an acceleration of 3.79 m/s². The cable from the crate passes over a solid cylindrical pulley at the top of the boom. The pulley has a mass of 108 kg. The cable is then wound onto a hollow cylindrical drum that is mounted on the deck of the crane. The mass of the drum is 190 kg, and its radius (the same as that of the pulley) is 0.449 m. The engine applies a counterclockwise torque to the drum in order to wind up the cable. What is the magnitude of this torque? Ignore the mass of the cable. Number i Units Pulley- Drum Boom
A 50 kg barrel with a diameter of .75 meters is placed on a 20° slope. Assuming the barrel rolls without slipping, what will the acceleration of the center of mass of the barrel be? (Solution: ax = 2.24 m/s²) 50 kg
An inclined plane of angle e = 20.0° has a spring of force constant k = 510 N/m fastened securely at the bottom so that the spring is parallel to the surface as shown in the figure below. A block of mass m = 2.61 kg is placed on the plane at a distance d = 0.297 m from the spring. From this position, the block is projected downward toward the spring with speed v = 0.750 m/s. By what distance is the spring compressed when the block momentarily comes to rest?

Block A (m = 5 kg), seen in the figure, sits on a smooth surface and is attached by a slender rod to a ball-and-socket joint at B. If the moment and force shown are simultaneously applied to the block, what will the speed of the block be after 4 seconds (starting from rest)?
A proposal is made to use a giant spring in the bottom of an elevator shaft as a means of safely "catching" a falling elevator car. The car freefalls until it hits a spring, which is then compressed until the car stops. The car's loaded weight is 20.0 kN. The elevator will service 20 floors. Distance between floors is 4 m. The deceleration rate of the car should not exceed 10 g's as it is being stopped. (a) determine the requirements for the spring constant and the amount the spring will compress in order to catch the falling car in the worst-case scenario. (b) what do you think about this proposal? Is it practical?
Can you please help me with all parts of the question? Thank you

h L/2 L/4 MR Ms A horizontal rod of length L and mass MR = 2.6 kg is used to hang a sign on a wall. The right end of the rod is attached to the wall by a hinge. A wire having tension T runs from the center of the rod to a place on the wall a distance h above the hinge as shown. The wire makes an angle 0 = 25° with the rod. The sign has mass Ms = 0.867 kg and hangs distance L/4 from the end of the rod. The system is in equilibrium. What is the tension T in the wire that runs between the wall and the rod? T = 60.35 N %3! T = 42.22 N %3D T = 14.08 N O T = 90.54 N T = 30.19 N %3! What is Fy, the vertical component of the force that the hinge exerts on the right end of the rod? A positive answer indicates an upward force and a negative answer indicates a downward force. Hint: Balance torques about an axis through the center of the rod. O Fy = -4.25 N Fy = 4.25 N Fy = -8.51 N Fy = -6.38 N Fy = 8.51 N
As shown in the figure, a 1.5 kg box is held at rest against a spring with a force constant k = 755 N/m that is compressed a distance d. Equilibrium position rough patch 6.0 cm When the box is released, it slides across a surface that is frictionless, except for a rough patch that has a coefficient of kinetic friction 0.40 Hk and is 6.0 cm in length. If the speed of the box is 1.6 m/s after sliding across the rough patch, determine the initial compression d (in cm) of the spring. cm
Let’s look at a simplified model of a car that’s dropped onto the ground. Model the suspension as a single linear spring and the rest of the vehicle as a single lumped mass. The car is dropped from a height of h1 = 0.9m. What is the maximum mass m for which the suspension does not bottom out? Assume a maximal allowable suspension travel of 10 cm and a spring constant of k = 2.4x10^6 N/m.
