Question

A bus starting from rest moves with a uniform acceleration of 01 m s2 for 2 minutes Find athe speed acquired b the distance travelled

Accepted Answer

aGiven the bust starts from rest Therefore initial velocity u 0 ms Acceleration a 01 ms2 Time 2 minutes 120 s Acceleration is given by the equation Therefore terminal velocity v 01 ms2 120s 0 ms1 12ms1 0 ms1 Therefore terminal velocity v 12ms bAs per the third motion equation 222 Since a 01 ms2 v 12 ms1 u 0 ms1 and t 120s the following value for s distance can be obtained Distance s 222 12202201 Therefore s 720m The speed acquired is 12ms1 and the total distance traveled is 720m
