Question
car driver engages a banked curve. In front of him is a truck. If the truck runs with optimum velocity that prevents skidding even in the presence of friction between the tire and the road, the car driver should: 33. A Run faster than the truck to reach the optimum velocity that prevents the skidding of his car Run slower than the truck to reach the optimum velocity that prevents the skidding of his car Run with the same speed as the truck because the skidding on a banked curve does not depend on the mass Keep a constant velocity None of the above a. b. c. d. e. 34. Two blocks of masses 20 kg and 8 kg are connected by a light string and rest on a frictionless level surface. Attached to the 8-kg mass is another light string, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s2 what is the tension in the connecting string between the blocks? a. 14N b. 6 N c. 10 N d. 4.0 N e. 1 N 35.Two blocks of masses 20 kg and 8 kg are connected by a light string and rest on a s level surface. Attached to the 8-kg mass is another light sring, which a person uses to pull both blocks horizontally. If the two-block system accelerates at 0.5 m/s2 what is the force used to pull this system of two objects? a. 28 N b. 20 N d. 14N e. 10 N 36. A force F is pushing on an object of mass m placed on an incline that make the angle with the horizontal. The force F is always oriented along the local horizontal and constant. If the friction is neglected, the acceleration with which the box is moving up (climbing) on the incline a. a gsinExplanation / Answer
33. optimum velocity is independent of mass of object.
it depends only on banking angle, friction coefficient and radius of curvature.
these quantity are same for both truck and car.
hence Ans: (c)
