Question

a bus starting from rest moves with uniform acceleration of 0.1 m/s2 for 2 mins .

find the speed accuired and distance travelled

Answer 1

we know that

v = u + at

here,

u = 0 [bus starts from rest, initial velocity will be zero]

a = 0.1 m/s²

t = 2min = 120s

so,

v = 0 + 0.1x120

thus, final velocity after 2min will be

v = 12 m/s

and also

s = ut + (1/2)at²

or

s = 0 + (1/2)x0.1x120²

thus, distance covered in 2min will be

s = 720 m
