The largest salami in the world was made in Norway. If a hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s, the centripetal acceleration of the mouse was 0.29 m/s^2. What was the radius of the salami?

Radius of the salami = 9.9 cm

Explanation:

The formula for calculating the radius is given below:

a = v^2/r

where a represents acceleration

v represents velocity

r represents radius

As hungry mouse ran around the salami's circumference with a tangential speed of 0.17 m/s so that means velocity = 0.17 m/s.

The centripetal acceleration of the mouse = 0.29 m/s^2

putting these values in the above formula, we get

0.29 = 0.17^2 / r

After rearranging, we get,

r = 0.17^2 / 0.29

r = 0.099 m

r = 9.9 cm

so the radius of the salami = 9.9 cm

the total distance traveled by the car is

30km + 49km = 79 km .
