Review. As shown in Figure P8.26, a light string that does not stretch changes from horizontal to vertical as it passes over the edge of a table. The string connects m1 , a 3.50- kg block originally at rest on the horizontal table at a height h = 1.20 m above the floor, to m2 , a hanging 1.90-kg block originally a distance d = 0.900 m above the floor. Neither the surface of the table nor its edge exerts a force of kinetic friction. The blocks start to move from rest. The sliding block m1 is projected horizontally after reaching the edge of the table. The hanging block m2 stops without bouncing when it strikes the floor. Consider the two blocks plus the Earth as the system. (a) Find the speed at which m1 leaves the edge of the table. (b) Find the impact speed of m1 on the floor. (c) What is the shortest length ofthe string so that it does not go taut while m1is in flight? (d) Is the energy of the systemwhen it is released from rest equal to the energy of the system just before m1…
Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below). Usually, the drawbridge is lowed to a horizontal position so that the end of
the bridge rests on the stone ledge. Unfortunately Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped it at 0 = 20.0° above the horizontal. The knight and
his horse stop when their combined center of mass is d = 1.00 m from the end of the bridge. The uniform bridge is = 6.00 m long and has a mass of 2 300 kg. The lift
cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h = 12.0 m above the bridge. Lost-a-Lot's mass combined with his
armor and steed is 1 200 kg.

- Three runaway train cars are moving on a frictionless, horizontal track in a railroad yard as shown in Figure P11.73. The first car, with mass m1 = 1.50 103 kg, is moving to the right with speed v1 = 10.0 m /s; the second car, with mass m2 = 2.50 103 kg, is moving to the left with speed v2 = 5.00 m/s, and the third car, with mass m3 = 1.20 103 kg, is moving to the left with speed v3 = 8.00 m /s.

- Nixon is a tile worker, he hates physics and only likes cutting and shaping his tiles. Her boss has given him a tile. It has a width of 50 cm. The tile must fit around a corner of a fireplace so a piece is sawed out. The extracted piece is a smaller square and its side length is only 25.0 cm. Because of the cutout segment, the center of mass of the ceramic tile shifts a bit from point A to point B. Nixon needs help to find the distance between point A and B the ceramic tile her boss gave him. 50cm 25cm 8 Sarrow_forwardA 1.6-kg block is attached to the end of a 2.0-m string to form a pendulum.
