A 10.0 kg box is tied to a rope and the rope is placed over a 5.00 kg pulley with a radius of 0.600 m. The pulley can be treated as a solid disk. A force is applied to the rope causing the box to accelerate up at 4.00 m/s². A. Calculate the tension in the rope between the pulley and the box. B. What is the magnitude of the force, F, being applied to the pulley? C. How far does the box move upward in 0.500 s if it starts from rest?

Q9 A Physics teacher is teaching a class about the effect of friction. They assemble a track that has a vertical loop of radius 30.0 cm. A toy car of mass 50.0 g is released from rest at a height of 1.00 m at the beginning of the track. The car rolls down the track and follows the loop before exiting the track. The teacher asks the class to calculate the speed of the toy car if the coefficient of friction were 0. Im 30 cm What is the calculated speed of the toy car as it reaches point X? (A) 1.49 ms (B) 2.21 ms! (C) 2.80 ms! (D) 7.84 ms

 To remove a nut from an old rusty bolts, you apply a 100 neutron force to the end of a wrench at a 45° angle to the wrench handle. The distance from the applied force to the axis of the bolt is 25 cm. what is the torque exerted on the bolt and N.m

a. What is the magnitude of acceleration of the block?   b. What is the magnitude of the tension force from the block on the cylinder?

V = 4 m/s ac µ = 0.1 Center of rotation R = 20 m Car around corner A 400 kg car is going around a curb as shown. The radius of the turn is 20 m and the car has a velocity of 4 m/s. The coefficient of friction between the tires and the road is 0.1 a. What is the angular velocity of the car? a. Will the car make the turn?

A point object with a mass of 150 g can move around a circular track that has a radius of 25 cm.
