Question

If a ladybug weighs 20g and is circling at a radius of 10 cm at 10 m/s, what is its centripetal acceleration m/s^2?

I know centripetal acceleration = velocity squared/r, and velocity = angular velocity * radius...

From these calculations I get 39476.089 m/s^2, which is wrong and seems unusually large.

What is the right procedure to do this?

Answer 1

2 m/s^2, is this correct

Answer 2

a=v^2/r so (10)^2/0.1= 10ms^-2

Answer 3

both are wrong...

Answer 4

a=v^2/r v in m/s, r in m

a=10^2/.1=1000m/s^2

Goodness, Ubaid, you need to stop helping others.

Answer 5

Thank you!
