Question

What is acceleration of the body if it starts from rest and travels at 92 km/hr in 5 min?

Answer 1

Initial velocity = 0km/h

Final velocity = 92 km/h

Time = 5 min

We will convert initial and final velocity into m/s

and time into seconds

u= 0km/h = 0 m/s

v = 92km/h =25.55 m/s

t= 5 m =5*60 =300 sec

Now using First Equation of Motion

v=u+at

92=0+a*300

92/300=a

a=0.30 m/s/s
