The momentum of the car is 60,000 kg m/s
Explanation:
The momentum of an object is a vector quantity, whose magnitude is given by
where
m is the mass of the object
v is its velocity
For the car in this problem, we have
m = 2,000 kg
v = 30 m/s
Therefore, the magnitude of its momentum is

Answer:
The answer is
<h2>7,840,000 J</h2>Explanation:
The kinetic energy KE of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 20000kg
v = 28 m/s
It's kinetic energy is
We have the final answer as
<h3>7,840,000 J</h3>Hope this helps you
