Question

A train is accelerating at a rate of 2 m/s. If its initial velocity is 20 m/s, what is its velocity after 30 seconds?

Answer 1

$\boxed{\bf{\blue{\implies Answer:}}}$

• v = u +at
• Here, u = 20 , a = 2 , t = 30secs
• Put this values in equation
• v = 20 + 60
• v = 80m/s2

Answer 2

Answer:

a= v -u

t

2= v-20

30

Find v..
