Question

A bus starting from rest moves with a uniform acceleration of 0.3m/s for 6 min .
Find its a) speed acquired b) distance travelled

Answer 1

Answer:

Distance = 19440 m

Speed = 54 m/s

Explanation:

u = 0

a = 0.3 = 3/10

t = 6 min = 360s

From equations of motion

s = ut + 1/2 at ^ 2

Since u = 0

= 1/2 at ^ 2

= 1/2 × 3/10 × 360 × 360

= 54 × 360

= 19440 m

Now,

Speed = Distance / Time

= 19440 / 360

= 54 m/s
