Question

What is the centripetal acceleration of an object spinning at 40 rad/sec at the end of a 520 cm string for 10s ?

Answer 1

Explanation:

formula for centripetal acceleration is

a = rw2

a= 520*(40)2

a= 520* 40*40

a= 832000 rad/sec2

Answer 2

Dear Student,

◆ Answer -

a = 8320 m/s^2

● Explanation -

# Given -

r = 520 cm = 5.2 m

w = 40 rad/s

# Solution -

Centripetal acceleration of an spinning object -

a = rw^2

a = 5.2 × 40^2

a = 5.2 × 1600

a = 8320 m/s^2

Hence, centripetal acceleration of an spinning object is 8320 m/s^2.

Thanks dear. Hope this helps you..
