Concept explainers
Two identical 40-lb curling stones have diameters of 11 in. and may slide on a sheet of ice. Stone B is at rest when stone A strikes it, moving it to the center of the inner circle. The distance A travels before striking B is 108 ft, and the sweepers scrubbing the ice reduce the coefficient of friction between A and the ice to 0.04, while the coefficient of kinetic friction between B and the ice is 0.1. The coefficient of restitution between A and B is 0.6. Neglecting rotation, and knowing that B travels 4 ft along the dotted line, determine (a) the distance b, (b) the speed A has when it is released 108 ft from the impact.

- 15 kg boxes are being transported around a curve via a conveyor belt as shown to the right. Assuming the curve has a radius of 3 meters and the boxes are traveling at a constant speed of 1 meter per second, what is the minimum required coefficient of friction needed to ensure the boxes don’t slip as they travel around the curve?arrow_forwardThe W1= 87.85-lb block shown rests on a smooth plane (coefficient of kinetic friction = 0) with an angle of 0 =28° from horizontal. It is connected by a flexible inextensible cord that passes around weightless, frictionless pulleys to a support. The W2 =109.85-lb weight is attached as shown. After the system is released from rest, in what distance will the block on the plain attain a speed of 6.7 ft/s? шш W2 W1arrow_forwardLuggage A is gently lowered with no initial velocity onto a moving baggage claim belt at Bradley International Airport in Hartford.

- (a) Two blocks are joined by an inextensible cable as shown in Figure. If the system is released from rest, determine the velocity of block A after it has moved 2 m by using the data given. Assume that the coefficient of kinetic friction between block A and the plane is ?k = 0.25 and that the pulley is weightless and frictionless.arrow_forwardA 10-lb bock is resting on an inclined surface at an angle of 30°, as shown. The block is in contact with a compressed spring that has a modulus of 75lb/in. The spring has an initial compression of 6 inches that is released by cutting the restraining cords. If the coefficient of kinetic friction between the inclined surface and the block is 0.15, determine the speed of the block as it leaves the spring. Position B L.
