A car accelerating, and then braking, while driving on an ice rink. You can see when braking is initiated because the front wheel momentarily stops rotating when the front bumper of the car is near the hockey stick laying on the ice.Determine the coefficient of friction between the Prius' tires and the ice.Because this car is equipped with anti-lock brakes, the wheels alternate between locked and rolling. We can use the car's motion to determine the effective, or average coefficient of friction during this motion. Hint: Can you tell from the video exactly when the driver begins to brake? The image depicts a winter scene with a car moving across a snowy landscape, featuring measurement markers and timing information. In the foreground, a ruler marked in meters is superimposed on the scene, beginning at 0 meters on the right and extending outward to 10 meters on the left with smaller increments marked. The ruler has black markings for the first half and red markings for the second half, likely for visibility or demarcation purposes.A woman is standing on the left, apparently holding a hockey goal. To the right is a car, specifically a hatchback model, positioned facing left. The car appears to be in motion, moving leftward across the scene.In the background, there are snowy trees and park structures like a gazebo and a small building, indicating a public park setting during wintertime.In the lower-left corner of the image, there is a label with timing information:- "4.6000 s" indicating the time elapsed.- "Frame 276" indicating the specific frame number.- "60 fps" showing the frame rate of the video, which is 60 frames per second.Below the image is a video control interface with play, pause, and skip buttons. The graph is titled "position of the car vs time" and displays the relationship between the position of a car and time. - The x-axis represents time in seconds (s), ranging from 0 to 4.5 seconds.- The y-axis represents the position of the car in meters (m), ranging from 0 to 18 meters.The data is plotted with green dots, indicating the measured points of the car's position over time. A green line smoothly connects these points, suggesting a continuous change in position. As time increases, the position of the car also increases, indicating motion along a path. The curve suggests the car's speed is increasing over time, which is characteristic of accelerated motion rather than constant speed. The chart also includes an option (gear icon) for potential adjustments or settings in the upper right corner.

Let a denotes the average acceleration, u denotes the speed just before the car brakes, and t…

Learning Goal: A 1290 -kg car is pushing an out-of-gear 2200 -kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push horizontally against the ground with a force of 4580 N. The rolling friction of the car can be neglected, but the heavier truck has a rolling friction of 755 N, including the "friction" of turning the truck's drivetrain. What is the magnitude of the force the car applies to the truck?

16. Running without friction is impossible. In fact, to maximize your acceleration, you need to maximize the static friction between your shoes and the floor. a) Explain why static friction is necessary for running or walking. requirement, employees' shoes must have a coefficient of static friction of 0.5 or more on a specified tile surface. In an emergency, what is the minimum time interval in which a postal worker starting from rest can move a distance of 3 m on the tile surface? c) A typical athletic shoe has a coefficient of static friction of 0.8 when used on a running track. What is the minimum time interval in which an athlete starting from rest can move a distance of 100 m on a running track? b) To meet a U.S. Postal Service
A 1700 kg car is driving down a highway at a constant velocity when a deer jumps out onto the road 59.6 m ahead. The coefficient of friction between the car tires and the road is 0.21. Calculate the initial velocity of the car if it is able to stop just before hitting the deer. (You do not need to account for reaction time of the driver. Assuming the car is breaking the entire 59.6 m distance and that friction is the only force stopping the car.) v0 = m/s
In a movie, a stuntman places himself on the vertical front of a truck as the truck accelerates. The coefficient of static friction between the stuntman and the truck is 0.370. The stuntman is not standing on anything but can “stick” to the front of the truck as long as the truck continues to accelerate. What minimum forward acceleration will keep the stuntman on the front of the truck?

Two small cylindrical plastic containers with flat bottoms are placed on a turntable that has a smooth flat surface. Canister A is empty; canister B is full. Each canister is the same distance r from the center. The coefficient of static friction between the canisters and the turntable is µs. The speed of the turntable is gradually increased. Describe what will happen. Include which container will fall off first or if they will fall off at the same time.
