Question

Q.4a) an object is tied to a rope and moves in a horizontal circle. The maximum tension in the rope is 100N. The object has a mass of 37kg and the rope is 1.4m long. what is the angle of the rope with respect to the Horizontal?
b) what is the speed of the object?
c) calculate the frequency of the object and the periodic time.

Answer 1

tension=w^2*r*mass
100=(2pi/period)^2*1.4*37
solve for period.

speed= 2PI*radius/period

f= 1/period

angle of object:
arctan mg/tension
