## Homework Statement

A toy truck moves around the outside of a circle of radius 0.6m at 2 revolutions per second

Calculate:

a: the angular speed of the truck

b: the linear speed of the truck

c: the period of revolution

## Homework Equations

[itex]

ω= \frac{2π}{T} \\

v=rω

[/itex]

??

## The Attempt at a Solution

For part a i have done..

[itex]

ω= \frac{2π}{T} \\

ω= \frac{2π}{0.5} \\

ω= 12.56 rads/s

[/itex]

I used 0.5 as it says it rotates twice per second so one rotation would take half a second (i think this maybe wrong).

For part b i have done..

[itex]

v=rω \\

v=0.6 \times 12.56 \\

v= 7.54m/s \\

[/itex]

Obviously this depends on whether I got part a correct.

For part c I am not sure what the question is asking for but at a guess I did what I did in part A..

2 revolutions per second, therefore 1 revolution would take 0.5s.

Any help is appreciated.
