Solution

The correct option is A
0.0185 m/s²

Initial speed of bus, u = 0 m/s

Final speed of the bus, v = 40 km/h = $40 \times (\frac{5}{18})$ m/s = 11.1 m/s

Time taken, t = 10 min = 600 s

Now, acceleration , a = $\frac{v - u}{t}$ = $\frac{11.1 - 0}{600}$ $m / s^{2}$ = 0.0185 $m / s^{2}$

A bus starting from rest and moving with a uniform acceleration attains a speed 40 km/h in 10 minutes. Find its acceleration.

The correct option is A 0.0185 m/s2 Initial speed of bus, u = 0 m/s Final speed of the bus, v = 40 km/h = 40×(518) m/s = 11.1 m/s Time taken, t = 10 min = 600 s Now, acceleration , a = v−ut = 11.1−0600 m/s2 = 0.0185 m/s2

The correct option is A
0.0185 m/s²

Initial speed of bus, u = 0 m/s

Final speed of the bus, v = 40 km/h = $40 \times (\frac{5}{18})$ m/s = 11.1 m/s

Time taken, t = 10 min = 600 s

Now, acceleration , a = $\frac{v - u}{t}$ = $\frac{11.1 - 0}{600}$ $m / s^{2}$ = 0.0185 $m / s^{2}$
