Answer:the answer can be find out by the following steps;
Explanation:
The acceleration of the car is [tex]3 m / s^{2}[/tex]. And the force required to reach the acceleration is 4500 N.
Explanation:
Equations of Motion describe different relations between motion parameters. One of them is,
[tex]v_{f}=v_{i}+a t[/tex]
And, [tex]F=m \times a[/tex] , from Newton’s laws
So, given,
Initial velocity of the car [tex]v_{i}[/tex] = 0
Mass of the car, m = 1500 kg
Velocity acquired [tex]v_{f}[/tex] = 15 m/s
Time taken to acquire velocity t = 5 seconds.
Now, since [tex]v_{f}=v_{i}+a t[/tex], To find the acceleration, rearrange the above equation, we get as follows,
[tex]a=\frac{\left(v_{f}-v_{i}\right)}{t}[/tex]
Then, by applying the given data in above equation, we get
[tex]a=\frac{(15-0)}{5}=\frac{15}{5}=3 m / s^{2}[/tex]
Now, find the force to reach [tex]3 m / s^{2}[/tex] acceleration as follows,
[tex]F=m \times a=1500 \times 3=4500 N[/tex]
