Acar that weighs 1.5 × 10^4 n is initially moving at a speed of 36 km/h when the brakes are applied and the car is brought to a stop in 17 m. assuming that the force that stops the car is constant, find (a) the magnitude of that force and (b) the time required for the change in speed. if the initial speed is doubled, and the car experiences the same force during the braking, by what factors are (c) the stopping distance and (d) the stopping time multiplied? (there could be a lesson here about the danger of driving at high speeds.)

Which statement is true about an object that is moving in a circular motion due to centripetal force, f, when the radius of its circular motion is doubled? the new force then becomes equal to 2f the new force then becomes equal to f the new force then becomes equal to f/2 the new force then becomes equal to f2 the new force then becomes equal to 1/f
