Question

You put a ball on the end of a string. You swing the ball

with a rotation speed of 5.6 m/s. The mass of the ball is
2.0 kg. The length of the string is 1.60 m. Calculate the
centripetal acceleration.​

Answer 1

`19.6 ms^(-2)`

Step-by-step explanation:

By the definition of centripetal acceleration ,

`a_c=(V^(2) )/(r)`

where ,

a = centripetal acceleration

V= velocity

r = radius of circle

`a_c=(V^(2) )/(r)[\\a_c=(5.6^(2) )/(1.6) \\=19.6 ms^(-2)`
