Albert is riding his scooter at a velocity of 80 km/h, when he sees an old woman crossing the road 45m away. He immediately steps hard on the brakes to get the maximum deceleration of 7.5m/s^2. How far will he go before stopping? Will he hit the old woman?

    Use: \[V_2^2 = V_1^2 + 2ad\] V2 = 0 Solve the equation for d, the distance. (the deceleration will be negative acceleration in this equation)
