Explanation:

A school bus traveling at 11.1m/s has a momentum of 152625 kg.m/s. What is the mass of the bus?

Answer 2

The mass of bus=13750 kg

Step-by-step explanation:

Momentum of bus= P =152625 kg

Speed of bus= v =40km/hr=

$\frac{5}{18} \times 40$

=

$11.1m/s$

Using

$1km/hour$

$= \frac{5}{18} m/s$

We know that

Momentum = P = mv

Using the formula

$152625 = m × 11.1$

$m = \frac{152625}{11.1}$

$m = 13750kg$

Hence the mass of the bus = 13750 kg
