Answer:
vf=at+v0. vf=0
-v0=at
t=-v0/a=(-27m/s)/(-8m/s^2)=3.4s
Explanation:
Given that,
Initial speed of a car, u = 60 km/h = 16.67 m/s
Acceleration, a = 2m/s²
Final speed, v = 120 km/h = 33.33 m/s
We need to find the distance traveled and the time taken to make the distance.
acceleration = rate of change of velocity

let the distance be d.

Hence, the distance traveled and the time taken to make the distance is 208.25 m and 8.33 seconds respectively.
Newton’s Second Law: Force = mass times acceleration.
F = 0.145 * 130
You would multiply to find the force required, not divide. Hope this helps!
25 m will be taken to stop the car
