Question

speed of car increases 18 kilometre per hour to 36 kilometre per hour in 10 seconds what is its acceleration​

Answer 1

Initial Velocity = u = 18 km / hr

Final Velocity = v = 36 km / hr

Time Taken = t = 10 seconds

Therefore,

Acceleration = (v - u) / t

                     = ( 36 - 18 ) / 10

                     = 18 / 10

                     =  1.8 metre per second square .
