Answer to Question #137218 in Classical Mechanics for Afraid

Question

A bus is moving with a= 5m/s2 from rest find its velocity after2sec.

Answer 1

solution

given data

initial velocity(u)=0 m/s

acceleration (a)=5 m/s^2

By using the first equation of motion

$v=u+at$

at t=2 sec it's velocity will be

$v=0+5\times2=10 m/s$

velocity after 2 second will be 10 m/s.
