Distance and Speed

The speed, distance and time relation forms the basis of study of motion. You will need these concepts in the study of Mechanics. This concept is applicable for students who are studying the following courses –

(A A person walks first at a constant speed of 4.80 m/s along a straight line from point to point and then back along the line from B to A at a constant speed of 3.05 m/s What is her average velocity over the entire trip? B m/s
Car A is traveling at 65 km/h when it enters a 50 km/h speed zone. The driver of car A decelerates at a rate of 20 m/s2 until reaching a speed of 50 km/h, which she then maintains. When car B, which was initially 20 m behind car A and traveling at a constant speed of 70 km/h, enters the speed zone, its driver decelerates at a rate of 25 m/s2 until reaching a speed of 48 km/h. Knowing that the driver of car B maintains a speed of 48 km/h, determine a) the closest that car B comes to ca A, b) the time at which car A is 25 m in front of car B.
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?
I need help solving this question. A rocket starting from rest rises vertically and accelerates at a constant rate of 13 m/s2 for 7 min. At this point the engine of the rocket accidently fails and completely shuts down. (Neglect air resistance and any variation in the acceleration due to gravity) a) What is the speed of the rocket when the engine shuts down? b) How high is the rocket above the ground at the point where the engine shuts down? c) How much higher will the rocket rise after the engine fails? d) What is the total time of the rocket in air? e) What is the average speed of the rocket for the entire trip?

He finds the car can accelerate from 0 to 60 mph (26.8 m/s) in 4.21 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 69.1 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?
You and your family are going on a road trip to visit your recently married cousin in B.C. The total round trip distance is 2100 km. On the way to B.C., you encounter no setbacks and you are able to drive on average at a constant speed. On the way home from B.C., you encounter a snowstorm and your mom has to slow down to avoid getting into an accident. Thus, your average speed decreases by 10 km/h. If the total driving time was 42 hours, what was your average speed on the way to B.C.? Recall distance = speed x time.
A person hits a trampoline while moving downward with a speed of 9 m/s and rebounds a short time later with roughly the same speed upward. If the person is in contact with the trampoline for about 1.8 s, what are the magnitude and direction of the person’s average acceleration during this time interval?
