Question

A bus starting from rest moves with a uniform acceleration of 0.5m/s2 for
4min.find the speed acquired and the distance travelled.

Answer 1

Answer: 120 m/s

Explanation:

Given that u = 0 m/s , a = 0.5 m/s² , t = 4 min = 4 × 60 = 240 s , v = ?

we know that ,

v = u + at    (first equation of motion)

substituting the values,

v = 0 + 0.5 × 240

v = 5 × 24

v = 120 m/s
