Question

Calculate the net force acting on a bus boarded with passenger, of mass 2000 kg moving with a uniform

velocity of 60 km/ℎr.​

Answer 1

Answer:

Initial velocity (u) = 0,

final velocity (v) = 10m/s,

time (t) = 5 second,

Mass (m) = 50 kg,

Therefore, force (F)=?

We know that, Force (F)

$= m \times \frac{v - u}{t}$

$f = 50kg \frac{10ms - 0 ) }{5s}$

$= f= 50kg \times {ms}^{ - 2}$

$= 100kg \: {ms}^{ - 2} = 100n$

Thus required force = 100 N
