a car is traveling at a constant speed of Vo on a straight, level road. After the brakes are applied at t=0 seconds, the motion can be approximated by: x=t^3/100-t^2 +17t
where x is the distance traveled in meters and t is the time in seconds. Determine:
A the initial velocity (Vo),
B. the time required for the car to stop,
C. The distance required for the car to stop, and
D. The maximum deceleration during braking.

A car is traveling with a constant speed when the driver suddenly applies the brakes, giving the car a deceleration of 3.50m/s2. The car comes to a stop in a distance of 34.0 m. What was an initial speed of the car? How long (the time) did it take for this car to stop? What was the car's speed when it had traveled 17.0 m from the point where the brakes were applied? How long did it take for this...

A ride-sharing car moving along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 32.0 m/s. Then the vehicle moves for 41.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the ride-sharing car in motion (in s)? 62 (b) What is the average velocity of the ride-sharing car for the motion described? (Enter the...

The driver of a car of mass M which is moving along a straight road with initial speed v0 sees a deer in her headlights, and reacts quickly, lifting her foot of the gas and applying the brake pedal with maximum force. The anti-lock brakes cause the largest possible static friction force to be applied on the tires by the road, which continue to roll so the car does not skid. The coefficient of static friction between the tires and...

10. A car is being driven along a straight, level highway at 71.582 mph. The driver taps on the brakes but notices no response. He tries to brake again and realizes the brakes are completely out. There is a field next to the highway with tall grass. The driver veers into the tall grass traveling in a straight line. The car eventually comes to a stop. Later it is measured that the car traveled 184 meters through the grass. How...

1. A car traveling at a speed of vo = 52 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 147 m. After the car has gone 1/3 of the stopping distance, what is its speed? v1/3 = 2. An athlete sprinter 50m in 9.3 seconds, and then walks slowly back to the starting line in total time of 58 seconds. (Assume he runs in the positive direction.) What is his average walking velocity? vav...
