Question

A traun starting from a railway station and moving with acceleration a speed 40 km/hr in 10 mint. Find acc

Answer 1

✔️speed=40km/hr

convert it in m/s

$40 \times \frac{1000}{3600} = \frac{100}{9} sec$
speed in m/sec. is 100/9

✔️time taken =10 minutes=600seconds

Now

using equation of motion
$v = u + at \\ \frac{100}{9} = 0 + a \: 600 \\ a = \frac{100}{9 \times 600} \\ a = \frac{1}{54} m {sec}^{ - 2}$
