A block of mass m=1.17kg is tied to a string and swings around in a vertical circle of radius R=1.60m.?
A block of mass m=1.17kg is tied to a string and swings around in a vertical circle of radius R=1.60m. The string will snap if it experiences a tension force above 88.2N. What is the maximum speed the block can have at the bottom of the circle?

g-force is mg: 1.17kg × 9.81m/s^2 = 11.48 Newtons
88.2 - 11.48 = 76.72 N
Centripetal force is mv^2/r
(76.72×1.6/1.17)^.5 = velocity = 10.24 m/s

88.2 = m*(g+V^2/r)
m*V^2/r = 88.2-1.17*9.8 = 76.73
V = √76.73*1.6/1.17 = 10.2 m/sec
