A 16 g ball at the end of a 1.4 m string is swung in a horizontal circle. It revolves once every 1.09 s. What is the magnitude of the string’s tension?

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

a=d/t

a="triangle"v/t

explanation:

a = acceleration

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
