Answer:
The speed v = 20m/s
Explanation:
m = 1.0 × 10³-kilogram
p = 2.0 × 10⁴ kilogram∙meters per second
v = ?
p = mv
===> v = p/m
v = 2.0 × 10⁴ ÷ 1.0 × 10³
v = 20m/s
The speed of the car is 20 m/s which has a mass of 1.0 × 10³ kg.
Momentum:
It can be defined as the product of the mass and velocity of an object. It is denoted by [tex]p[/tex] .
[tex]p = mv[/tex]
Where,
[tex]p[/tex] - momentum = 2.0 × 10⁴ kgm/s
[tex]m[/tex] - mass = 1.0 × 10³ kg
[tex]v[/tex] - velocity = ?
Put the values in the formula,
[tex]\begin {aligned}2.0 \times 10^4& = 1.0 \times 10^3 \times v\\\\v&= \dfrac { 2.0 \times 10^4}{1.0 \times 10^3 }\\\\v& = 20 \end {aligned}[/tex]
Therefore, the speed of the car is 20 m/s.
