Question

A car is traveling at a speed of 10m/s. A 0.5kg clump of mudis

stuck to the outside edge of the tire, which as a radius of0.2m.
What force is acting on the mud, keeping it from flyingoff?
A.) 250 N outward
B.) 250 N inward
C.) 25 N outward
D.) 25 N inward
E.) 40 N inward
Answer and explanation would be great. If you are not
sure,please do not answer.

Answer 1

Answer:B

Step-by-step explanation:

Given

speed of car
`v=10 m/s`

mass of clump
`m=0.5 kg`

Radius of car tire
`r=0.2 m`

Since the tire is rotating about axle so a centripetal force is acting constantly on each particle towards the center of tire.

Centripetal force is given by

`F_c=(mv^2)/(r)`

where
`m=mass\ of\ element`

`v=speed`

`r=distance\ from\ center`

`F_c=(0.5* 10^2)/(0.2)`

`F_c=250\ N` (inward)
