<h3><u>Question</u><u>:</u></h3>
A racing car is travelling at 70 m/s and accelerates at -14 m/s^2. What would the car’s speed be after 3 s?
<h3><u>Statement:</u></h3>
A racing car is travelling at 70 m/s and accelerates at -14 m/s^2.
<h3><u>Solution</u><u>:</u></h3>
- Initial velocity (u) = 70 m/s
- Acceleration (a) = -14 m/s^2
- Time (t) = 3 s
- Let the velocity of the car after 3 s be v m/s
- By using the formula,
v = u + at, we have
- So, the velocity of the car after 3 s is 28 m/s.
<h3><u>Answer:</u></h3>
The car's speed after 3 s is 28 m/s.
Hope it helps
Dna is the way to answer this questions
I think it's 45 miles. Don't know for sure though

I think the the answer would be no. </span> If the instantaneous speed of an object remains constant, then its instantaneous velocity would not change. S<span>ince v = c for c is some constant, then |v| = |c|. This is regardless of the sign of c. Hope this answers the question.</span>
It is definitely the first law, the first law is the law of inertia. It states that an object remains in its state of rest or uniform motion on a straight line except compelled by an external force. The planet remains in its position because there is no external force acting on it which will make it move. Hope i helped. have a nice day<span />
