Question

Question 1, chap 106, sect 1. part 1 of 2 10 points An air puck of mass 0.030 kg is tied to a string and allowed to revolve in a circle of radius 1.1 m on a frictionless horizontal surface. The other end of the string passes through a hole in the center of the surface, and a mass of 1.9 kg is tied to it, as shown in the figure. The suspended mass remains in equilibrium while the puck revolves on the surface The acceleration of gravity is 9.81 m/s 0.03 kg 1.9 kg a) What is the magnitude of the force that maintains circular motion acting on the puck? Answer in units of N Question 2, chap 106, sect 1 part 2 of 2 10 points b) What is the linear speed of the puck? Answer in units of m/s.

Explanation / Answer

here,

mass , m = 0.03 kg

radius , r = 1.1 m

suspended mass , m' = 1.9 kg

as they are in equilibrium

the magnitude of force required for circular motion = tension in the string

F = m'*g = 18.6 N

b)

let the linear speed be v

F = m *v^2 /r

18.6 = 0.03 * v^2 /1.1

v = 26.1 m/s
