Mr Sprayberry is running late to school. The speed limit is 40 miles per hour, and he is stopped at a stop light. After the light turns green, he accelarates at 5.2 m/s for 19 seconds. Is he speeding a the end of his accelaration? What would his acceleration be for those 90 seconds in order to reach exactly 40 miles per hour?

1) Starting in Albany, you travel a distance 461 miles in a direction 19.4 degrees north of west. Then, from this new position, you travel another distance 132 miles in a direction 10.2 degrees north of east. In your final position, what is your displacement from Albany? 2) You start out by driving 119 miles north in 3 hours and 41 minutes, and then you stop and park for a while. Finally you drive another 88 miles south in 4...

A car travels 40 miles in 30 minutes. a. What is the average velocity in kilometers/hour? b. If the car weighs 1.5 tons, what is its kinetic energy in joules (Note: you will need to convert your velocity to m/s)? c. When the driver applies the brake, it takes 15 seconds to stop. How far does the car travel (in meters) while stopping? d. What is the average acceleration of the car (in m/s2) during braking?
