A driver of an ambulance going 70km/hr suddenly sees another car 35.0 m ahead. It takes the driver 0.62 s before he applies the brakes. Once he begins to brake, he reduces speed at a rate of 13.0 m/second squares. Determine if the driver will hit the car or not
An observer riding on the platform measures the angle q that the thread supporting the light ball makes with the vertical. There is no friction anywhere. If you can vary m1 and m2, find the largest angle q you could achieve.
