On dry concrete, a car can decelerate at a rate of 7.00 m/s^2, whereas on wet concrete it can decelerate at only 5.00 m/s^2. Find the distances necessary to stop a car moving at 30.0 m/s (about 110km/h) (a) on dry concrete and (b) on wet concrete. (c) Repeat both calculations, finding the displacement from the poiint where the driver sees a traffic light turn red, taking into account his reaction time of 0.500 s to get his foot on the brake.

A car accelerates from rest at a rate of 2.2 m/s^2 for 14.3s. The car then holds this speed for 16.0s, after which there is an acceleration of -3.0 m/s^2 until the car comes to rest. a) Sketch a position vs. time graph for the car b) Sketch a velocity vs, time graph for the car c) What is the total distance traveled by the car?

Cranberries can be harvested using either a "wet" method or a "dry" method. Dry-harvested cranberries can be sold at a premium, while wet-harvested cranberries are used mainly for cranberry juice and bring in less revenue. Fresh Made Cranberry Cooperative must decide how much of its cranberry crop should be harvested wet and how much should be dry harvested. Fresh Made has 5,000 barrels of cranberries that can be harvested using either the wet or dry method. Dry cranberries are sold...

A race car starts from rest, accelerates at a constant rate of 3.8 m/s^2 for 23s, and then brakes (decelerates) at a constant rate of 5.6 m/s^2 (magnitude) until it comes to a stop. (a) Find the total distance traveled by the car before coming to rest. (b) Draw a graph of the velocity vs. time, and indicate numerical values of any “special points”on the graph.

A car traveling 37.0 m/s overtakes another car going only 21.0 m/s. When the faster car is still behind the slower one, it sounds a horn of frequency 1400.0Hz. What is the frequency heard by the driver of the slower car?

a). A prototype car starts from rest and accelerates at a constant rate to 30 m/s in 5.6 seconds. How much distance did the car travel during the 5.6-second accelerated motion? b). A car was parked on the side of a hillside road at the top of a hill. Unbeknown to the owner, its parking brake failed and tremors from nearby construction set it in motion with negligible initial speed down the hill. Assume the acceleration was constant down the...

a). A prototype car starts from rest and accelerates at a constant rate to 60 m/s in 4.1 seconds. How much distance did the car travel during the 4.1-second accelerated motion? b). A single-engine air plain starts its engine at one end of the runway. It accelerates at a constant rate and takes off at 36 m/s after 29 seconds on the runway, just as it is running out of runway. How long is the runway? c). An object is...

Part A If a car has a linear acceleration of 1.8 m/s^2 and the radius of its wheels is 0.33 m, what is the angular acceleration of the wheels? a. 0.18 rad/s 2 b. 0.59 rad/s 2 c. 5.5 rad/s 2 d. 9.8 rad/s 2 Part B Given the angular acceleration in the previous problem, how many revolutions does one of the car’s wheels complete in 10.0 s? Assume the car is initially at rest.
