Question

which diagram correctly shows the direction of the normal and gravitational i forces on the car making a turn on a banked road? 2.The net force on the cart at point c is A) N+mg B) N-mg C) N F Both Choice Aand E D) mg 3. A roller coaster car (above) is on a track that forms a circular loop of radius R in the vertical plane. lf the car is to just maintain contact with track at the top of the loop, what is the minimum value for its velocity at this point? E.(RR) B, 0.5 RR C. RR A. gR 4. A box is placed on the noor at the edge of a merry-go-round of radius 4.0 m The coefficient of static friction between the bow and the noor is 0.10, Determin the maximum tangential speed of the merry-go-round so that the box does not slide off. c 3 ms D. s m s E. 10 m/s

Explanation / Answer

Q1.
Option d is correct.
The road exerts normal force perpendicular to its surface. And the downward force of the weight w=mg is present. These forces add up to provide a net force which points toward the center which is the centripetal force.
