mv^2 / r = F
The Attempt at a Solution
This is my attempt and reasoning for this problem, is this the correct way to approach the problem or am i missing something?the hanging mass is motionless the tension in string equals the force of gravity on mass m2, therefore
T = 4*9.8N
The horizontal force on the puck (which is the centripetal force) is the same as the tension.
F(horizontal) = 4*9.8 N
(c) mv^2 / r = F(centripetal) ===> (0.8)(v^2) / (1.5) = 4*9.8 ===> v = 8.57321 m/s
