Three blocks (as shown in the figure) are released from rest and they start to accelerate with a constant magnitude of 0.44 m/s². Block A has mass M, block B has mass 1.8 M and block C has mass 2.0M. The value of M is not given. What is the coefficient of kinetic friction between the table and block B? The mass and friction in the pulleys can be ignored. A Question Help: Read Submit Question B C

Learning Goal: A 1290 -kg car is pushing an out-of-gear 2200 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4580 N. The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 755 N, including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck?

Jeanine, who has a mass of 45 kg, rode a roller coaster through a loop with a radius of 35 km . Assume the roller coaster maintained a constant speed of 48m/s. Draw a free-body diagram of the scenario below. Include the forces at the: • top • bottom • sides

A child of mass m rides on a Ferris wheel as shown in figure (a). The child moves in a vertical circle of radius 12.2 m at a constant speed of 2.75 m/s. a circular path at a constant speed. To yield net force vectors with the same magnitude, the normal force at the bottom must be ---Select-- v that at the top. Categorize Because the speed of the child is constant, we can categorize this problem as one involving a particle (the child) ---Select- v, complicated by the gravitational force acting at all times on the child. Тор , Analyze (Use the following as necessary: not m, and g.) We draw a diagram of forces acting on the child at the bottom of the ride as shown in figure (b). The only forces acting on him are the downward gravitational force F, = mg and the upward force n exerted by the seat. The net upward force on the child that provides his centripetal acceleration has a magnitude Fnet.bottom mg Using the particle in uniform circular motion model, apply Newton's second law to the…

The Colussus is a ferris wheel at 6 Flags amusement park with a 50.4 m diameter. It rotates at 1.5 rpm. For the following, assume the rider has a mass m = 65 kg, and that the rider sits forward with feet up so the only part of the seat that exerts a force on the rider is the horizontal seat bottom. As usual, a free body diagram is a great place to start. Find the normal force exerted by a seat on a person riding the Colossus at the highest point in the ride. Hint: the speed of the rider can be computed from the circumference of their circular path and the time it takes to make one full revolution. Find the normal force exerted by a seat on a person riding the Colossus at the lowest point in the ride.

A car of mass m is negotiating a circular turn of radius R and speed v on a banked road with an angle of banking θ. The forces on the car are shown below. Ignore friction in this problem.   Draw a free body of the car. Identify and show the radial direction. Pick coordinate axes with x pointing in the radial direction towards the center of the circle and y in the vertical direction. Show the coordinate axes on the free body diagram. Set up Newton’s Laws in the radial and vertical direction. Which force provides the centripetal force? Use the equations in part C to solve for the speed of the car in terms of R, Does the speed depend on the mass of the car? If  R=250.0 m, m=750.0 kg, calculate the speed of the car.

The 7.4 lb block has a speed of V = 2.4 ft/s to the left when the force of F = (3.6t3) lb is applied to the right. Determine the velocity and position of the block when t = 0.2 sec. The coefficient of kinetic friction at the surface is uy = 0.2. Provide both the Free-Body-Diagram and the Kinetic-Diagram. V F= (3.6t) lb
