An automobile driver took a curve too fast. The car spun out of control about its center of gravity (CG) and slid off the road in a northeasterly direction. The friction of the skidding tires provided a 0.25 g linear deceleration. The car rotated at 100 rpm. When the car hit the tree head-on at 30 mph, it took 0.1 sec to come to rest. The force exerted by the 100-lb child on her seatbelt harness as a result of the acceleration just prior to impact is 875 lbf 618 lbf 657 lbf 725 lbf

The system shown below consists of a uniform disk D that has a mass of mp = 3.0 kg and a radius of r = 0.5 meters. The disk is connected by a massless cable to a block. The system is released from rest and the disk starts rolling without sliding with the angular acceleration of a = 24 rad in the clockwise direction. Determine the tension developed in the cable (in Newtons) at this instant. Consider 0 = 30° and g 10 * mp
In a conceptual design, the power to move a bus comes from the energy stored in an onboard rotating flywheel. The flywheel has a mass of 1500 kg, a radius of gyration of 500 mm, and is brought to a maximum speed of 4000 rpm. If the bus starts from rest and acquires a speed of 72 kph at the top of a hill 20 m above the starting position, find the reduced speed of the flywheel. Assume 10% of the energy of the flywheel is lost due to frictional effects. Neglect the energy of the bus contained in the rotation of the wheels. The bus with flywheel is 10,000 kg.

A spherical bowling ball with mass m = 4.6 kg and radius R = 0.105 m is thrown down the lane with an initial speed of v = 9.5 m/s. The coefficient of static friction between the ball and the ground is 0.35 and the coefficient for kinetic friction is μ = 0.3. Once the ball begins to roll without slipping it moves with a constant velocity down the lane. 1) What is the magnitude of the angular acceleration of the bowling ball as it slides down the lane? 2) What is magnitude of the linear acceleration of the bowling ball as it slides down the lane? 3) How long does it take the bowling ball to begin rolling without slipping? 4) Once it begins to roll without slipping, what is the force of friction on the ball?

A cart has a mass of 1.5 kg. It is given some initial push toward a sensor and is slowed by a hanging mass which makes the cart turn around and speed up as it returns to its original position. This situation is illustrated in the attached image. If the acceleration towards the sensor is 0.5 m/s2 and the accaleration away from the sensor is 0.15 m/s2, a. draw the free body diagrams for the cart moving towards the sensor and away from the sensor. b. Write Newton's law for both situations and solve for the frictional force and for the force from the hanging mass.
1. (bold type indicates a vector) An object of mass m = 10 kg may rotate in a vertical plane about the fixed point P under the action of gravity. The distance d from the point P to the center of mass C is d = 0.5 m. The moment of inertia Ie about the center of mass C is unknown. The object starts at rest in the position shown and is then released. At the instant of release the acceleration of the center of mass is measured to be a, = (-5 m/sec²)j (i.e., downward). Use the given information to determine the moment of inertià I, about the center of mass. Use g = 10 m/sec?. gravity w go P (f ixed)
