A car starts from rest and accelerates to a speed of "a" mph in "c" seconds. The acceleration during this period is constant. For the next "d" minutes the car moves with the constant speed of "a" mph. At this time, the car decelerates to a speed of "b" mph in "e" seconds. Then for the next "f" minutes the car moves with a constant speed of "b" mph. At this time the driver of the car applies the brake and the car decelerates to a full stop in "g" seconds. The variation of the speed of the car with time is shown in the accompanying diagram. Determine the total distance (miles) traveled by the car and the average speed (kph) of the car over this distance. a = 50 mph b = 30 mph 30 seconds d = 30 minutes e = 20 seconds 25 minutes f3= 10 seconds

A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.

A driver is driving uphill. He maintained his throttle, causing his car to constantly decelerate as it is coming up the hill. The road going up the hill is 217 m long and it took him 8.8 seconds to get to the top of the hill. His speed has reduced to 22 m/s at that point. What was the car's acceleration (include a negative sign in your answer)? Hint: the initial position of the car can be set at the origin.

Fast Car: On a hot day in the flats, the temperature is 103.6 degrees. A driver finds an empty, flat stretch of desert that is 1776 meters long and decides to push the limits of his car. He finds the car can accelerate from 0 to 60 mph (26.8 m/s) in 4.30 s. Now he wants to see how fast the car can go. Assume the car maintains the same average acceleration until it reaches its top speed of 84.8 m/s. (a) How long will it take the car to reach its top speed? (b) How far will the car travel before it reaches its top speed?

A train starts from rest and accelerates uniformly, until it has traveled 5.6 km and acquired a velocity of 42 ms. The train then moves at a constant velocity of 42 m/s for 420 s. The train then slows down uniformly at 0.065 m/s2, until it is brought to a halt. The acceleration during the first 5.6 km of travel is closest to: O 0.20 m/s² O 0.14 m/s² O 0.19 m/s² 0.17 m/s² O 0.16 m/s²
