Question

A bus starting from rest moving with a uniform acceleration of 0.1 metre second square for 2 minutes a.) find speed acquired b.) distance travelled and in this time

Answer 1

Hey.

Here is the answer.

u = 0

a = 0.1 m/s^2

t = 2 minutes = 2×60 =120 s

a) as V = u + a t

so, speed acquired, v = 0 + 0.1×120= 12m/s

b) distance travelled in this time ,

s = u t + 1/2 a t ^2

or, s = 0 + 1/2 ×0.1× 120^2 = 720 m

Thanks
