A bus starts from the stop and take 50 second to get the speed of 10m/s. If the mass of the bus along with passengers is 10000 kg, calculate the force applied (in N) by the engine of bus to push the bus to the speed of 10m/s?

Solution

According to the question:

Initial velocity (u) = 0, final velocity (v) = 10m/s, time (t) = 50 second, Mass (m) = 10000 kg,

Therefore, force (F)=?

We know that, Force (F) = m $\frac{v - u}{t}$
Therefore, F = 10000 kg $\frac{10 - 0}{50}$
⇒ 10000 kg x $\frac{1}{5}$ ms^-2

F = 2000 kgms^-2 or, 2000 N

Thus required force = 2000 N
