A car begins decelerating at 2 m/s2 and takes 30 meters to stop. How long did the car take to stop?≈ 5.5 s≈ 7.5 s ≈ 4.5 s≈ 8.5 s
Question
Solution 1
To solve this problem, we can use the equation of motion: v^2 = u^2 + 2as, where:
v = final velocity = 0 (since the car stops) u = initial velocity (which we need to find) a = acceleration = -2 m/s^2 (negative since it's deceleration) s = distance = 30 m
