Suppose the car now accelerates from 0 m/s to 30.0 m/s in 5.00 s. if the wheels have a radius of 24.1 cm, what is their angular acceleration?

6.00 rad/s-2
125 rad/s2
0.25 rad/s2
25.0 rad/s

Explanation:

First of all, we can calculate the tangential acceleration fo a point on the wheels, which is given by

where

v = 30.0 m/s is the final velocity

u = 0 m/s is the initial velocity

t = 5.00 s is the time taken

Substituting,

Now we can find the angular acceleration by using the following equation

where

a is the tangential acceleration

r = 24.1 cm = 0.241 m is the radius of the wheels

Substituting into the formula,

massxgravity x heght=weightxheight= pe

4900=490xh

h=10
