Question

A particles of mass 0.4 kg is attached to one end of a string of length 90cm. The particle moves in a horizontal circle with angular velocity of 2.5m/s with the string inclined at an angle of the vertical. Find The Angle. [g = 10 m/s2

Answer 1

Answer:

m=150g=0.150kg,r=25cm=0.25m,h=90cm=0.90m
