You are traveling on an interstate highway at the posted speed limit of 70 mph when you see that the traffic in front of you has stopped due to an accident up ahead. You step on your brakes to slow down as quickly as possible. Assume that you to slow down to 30 mph in about 5 seconds. A) With this same average acceleration, how much longer would it take you to stop?B) What total distance would you travel from when you first apply the brakes until the car stops?
A.The time taken for the car to stop is 8.75 s
B.The distance travelled when the brakes were applied till the car stops is 136.89 m
A. Determination of the time taken for the car to stop.
Listed following are locations and times atwhich different phases of the Moon are visible fromEarth’s....? Listed following are locations and times atwhich different phases of the Moon are visible from Earth’sNorthern Hemisphere. Match these to the appropriate moon phase.
The three given moon phases are:
Waxing Crescent Moon
Waning Crescent Moon
The things we need to match to the above three topicsare:
*visible near western horizon an hour after sunset *rises about the same time the sun sets *visible near eastern horizon just before sun rises *occurs about 3 days before new moon (i know this is waningcrescent) *visible due south at midnite *occurs 14 days after new moon (i know this is full moon)
*visible near western horizon an hour aftersunset WAXING CRESCENT
*rises about the same time the sun sets FULLMOON
*visible near eastern horizon just before sun rises WANING CRESCENT
*occurs about 3 days before new moon WANING CRESCENT
*visible due south at midnite FULL MOON
*occurs 14 days after new moon FULL MOON
Explain what happent to the pressure exerted by an object when the area over which it is exerted:a) increase b) decrease
The pressure decreases if the area increases. If the area decreases then the pressure increases.
The 160-lblb crate is supported by cables ABAB, ACAC, and ADAD. Determine the tension in these wire
Using the diagram (see attachment) we extract the following position vectors:
Next step is to find unit vectors as follows:
Using the diagram we find the corresponding vectors Forces:
Equation of Equilibrium:
Comparing i , j and k components as follows:
Solving Above equation simultaneously we get:
