Question

a bus of mass 2500 kg has a momentum of 1250kg m/second.
calculate the velocity of the bus. ​

Answer 1

Given,

Mass of bus = 2500 kg

Momentum = 1250 kg m/s

To find,

Velocity of bus (v)

Solution,

We can simply solve this numerical problem by doing as follows:

Now,

Mass of bus = 2500 kg

Momentum = 1250 kg m/s

Velocity of bus (v) = ?

(Since, all of the physical quantities are in SI units, there is no need to do any conversion)

According to the kinematics,

Momentum = Mass x velocity

M = m x v

Therefore,

v = M/m

v = 1250/2500

v = 0.5

v = 0.5 m/s

Hence, the velocity of the bus is 0.5 m/s.
