Question

find the velocity of the moving carwhen the mass is 450 kg andmomentum is 1200 kgm/s 1. 2.8 m/s2. 2.6 m/s

Answer 1

Given:

Mass, m = 450 kg

Momentum, p = 1200 kg.m/s

Let's find the velocity.

To find the velocity, apply the momentum formula:

`\rho=m*v`

Where:

• p is the momentum

,

• m is the mass in kg

,

• v is the velocity in m/s

Plug in the values and solve for v:

`\begin{gathered} 1200=450*v \\ \\ \text{ Divide both sides by 450:} \\ (1200)/(450)=(450v)/(450) \\ \\ 2.6\text{ = v} \\ \\ v=2.6\text{ m/s} \end{gathered}`

Therefore, the velocity of moving car is 2.6 m/s.

ANSWER:

2.6 m/s
