Question

You whirl a stone tied to the end of the rope in a horizontal circle at constant speed, as shown in the diagram below. Use the direction rosette to answer the following questions.

You whirl a stone tied to the end of the rope in a horizontal circle at constant speed, as shown in the diagram below. Use the direction rosette to answer the following questions. What is the direction of the velocity vector when the stone is at location C? What is the direction of the velocity vector when the stone is at location B? What is the direction of ?v vector as the stone moves from location C to location B? What is the direction of the centripetal force acting on the stone for its motion from location C to location B?

Explanation / Answer

(a) 5

(b) 7

(c) 8 (reason: del(v)= Vb - Vc)

(d) 8 (reason: on moving from C to B centrifugal force goes from 7 to 1 thus on an average 8)
