Question

A bus starting from rest moves with a uniform acceleration of 0.1 m/ s for 2 minutes.find the speed
required

Answer 1

v = u+at
v = 0+0.1*120 seconds
v = 12 m/s

Final velocity will be 12 m/s.

Answer 2

Given that,

initial velocity (u) = 0 m/s

final velocity (v) = v

acceleration (a) = 0.1 m/s²

time taken (t) = 2 minutes = 120 s

According to Newton's first equation of motion,

v = u + at

⇒v = 0 + 0.1 × 120

⇒v = 12 m/s

so, the final velocity / speed = 12 m/s
