2.10 A car is going 35 m/s when the driver applies the brakes. a) If the braking acceleration is −5.7 m/s2 , how far will the car go as its velocity drops from 35 m/s to 22 m/s? b) How much time will the change from 35 m/s to 22 m/s take? 2.11 As hockey puck slides to a stop, it goes 40 m across the ice in 3.7 s. a) What was the initial velocity of the puck? b)...
A 1200-kg car going 30 m/s applies its brakes and skids to rest. If the friction force between the sliding tires and the pavement is 6000 N, how far does the car skid before coming to rest? Can you help me get the formula to use . Thanks
A car starts from rest and travels for 10.0 s with a uniform acceleration of +1.8 m/s2. The driver then applies the brakes, causing a uniform acceleration of -2.5 m/s2. If the brakes are applied for 2.0 s, determine each of the following. (a) How fast is the car going at the end of the braking period? m/s (b) How far has the car gone? Om Need Help? Read It

A driver in a moving car applies the brakes. The car slows to a final speed of 1.30 m/s over a distance of 40.0 m and a time interval of 8.20 s. The acceleration while braking is approximately constant. (a) What is the car's original speed before braking? What is its acceleration during this time? (The car's initial velocity is in the positive direction. Indicate the direction with the sign of your answer.)
(20 points) A car starting from rest travels 220 m in 9.4 seconds with a constant acceleration. It then travels at a constant speed for another 12 seconds. After that, the brakes are applied and the car comes to rest an acceleration of 6.5 m/s2. A) Draw the motion diagram for the entire trip. B) What direction is the acceleration when the car is coming to rest? C) List all known variables with their values. D) What is the acceleration...
