Question

A tran starting from stationary position and moving with uniform acceleration attain a speed of 36km per house in 10 minutes find its acceleration

Answer 1

according to equation of motion;

Final velocity(m/s) = Initial velocity(m/s) + acceleration*time(m/s² *s)

Given data; initial velocity = 0 m/s (starts from rest)

final velocity = 36 km/hr = (36*1000)/3600 m/s = 10 m/s

time = 10 mins = 10*60 secs = 600 secs

now substituting the data into the equation of motion

10 = 0 +a*(600)

a = 0.01667 m/s²
