Answer:
final velocity squared = initial velocity squared + 2 * acceleration * distance
Since the car is coming to a stop, the final velocity is 0 m/s. The initial velocity is not given, so we assume it to be 0 m/s as well. The acceleration is -7 m/s^2 and the distance is 150 m.
Using the equation, we can solve for time:
0 = 0 + 2 * (-7) * 150
Simplifying the equation, we get:
0 = -2100
Since this equation has no solution, it means that the car cannot come to a complete stop with the given acceleration and distance.
