What is the momentum of a 950 kg car moving at 10.0 m/s?
2 answers:
Answer:
Momentum of the car, p = 9500 kg-m/s.
Explanation:
It is given that,
Mass of the car, m = 950 kg
Velocity of the car, v = 10 m/s
We need to find the momentum of the car. It is given by the product of mass and velocity. It is given by :
p = 9500 kg-m/s
So, the momentum of the car is 9500 kg-m/s. Hence, this is the required solution.

<u>Answer</u>
The acceleration is
to the nearest tenth
<u>Explanation</u>
Since the car was travelling at before it starts to decelerate, the initial velocity is
.
The final velocity is , because the car came to a stop.
The time taken is .
Using the Newton's equation of linear motion,
, we find the acceleration by substituting the known values.
This implies that,
This gives us,
We divide both sides by 15 to get,
or
