Question

A certain string can withstand a maximum tension of 55N before breaking.What is the maximum speed at which we can safely swing a 1.0 kg mass on a piece of this string 0.50m long in a horizontal circle?​

Answer 1

Step-by-step explanation:

Fmax = Fc = mv^2/r

`m \frac{ {v}^(2) }{r} = f\frac{}{max} \\ {v}^(2) = ((0.50 \: m)(55 \: n))/(1.0 \: kg) = 27.5 \: \frac{ {m}^(2) }{ {s}^(2) } \\ v = 5.2 \: (m)/(s)`
