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

R Rod Block Bullet Problem 7: The puck in the figure above on the left has a mass of 0.120 kg. The distance of the puck from the center of rotation is originally 0.4 m, and the puck is sliding with a speed of v; = 0.8 m/sec. The string is pulled downward through the hole in the frictionless table and the new distance of the puck from the center of rotation is 0.25 m. What is the new speed of the puck? Answer: vf = 1.28 m/sec Problem 8: In the figure above on the right a 0.001 kg bullet with initial speed vi = 1800 m/sec is fired into a 0.5 kg block attached to the end of a 0.60 m rod of mass 0.50 kg. Point A is the pivot point for the rod and the bullet stays inside the block after the collision. What is the angular speed w of the system after the collision? The moment of inertia of the rod about point A is I = Me and the moment of a particle is I = mr?. Treat the block as a particle and also treat the bullet as a particle. Answer: w = 4.5 rad/sec

Your workouts are helping, and now, you can finally do one pull-up.In the pull-up, you lift your body's Center-of-Mass (C.M.) by 0.5 m in2 seconds. If your weight is W = 666 N, how much power did youexpend in the process?

PRINTER VERSION 4 ВАСК NEXT Chapter 08, Problem 069 Z Your answer is partially correct. Try again. In the figure the pulley has negligible mass, and both it and the inclined plane are frictionless. Block A has a mass of 1.0 kg, block B has a mass of 2.2 kg, and angle 0 is 27 °. If the blocks are released from rest with the connecting cord taut, what is their total kinetic energy when block B has fallen 21 cm?

The dog stole the baby's dirty diaper that Kristan had just changed and was getting ready to throw away. The dog weighs 15kg and the diaper weighs 2kg. The dog runs outside and climbs up the stairs to the playhouse where it accidentally steps a little too far in the slide causing the dog to slide down the slide with the diaper in his mouth. The height of the slide is 1.5m high off the ground. What is the change of potential energy of the dog assuming it started at rest and slid all the way to the ground?
