Referring to the figure, a truck drives a distance d=30.1m in the positive x direction in a time t1=17.2s, at which point the truck brakes, coming to rest in t2=8.13s. Part A: What is the truck's average velocity in the horizontal direction, in meters per second, during the t1 time period? Part B: Assuming the truck started from rest and moved with a constant acceleration, what was the acceleration, in meters per suqared second, during the time interval t1? Part C: What was the truck's instananeous velocity in the horizontal direction, in meters per second, when it began braking? And using the result from the previous answer, what was the truck's horizontal component of acceleration, in meters per squared second, during the braking period? Please explain how you got your answer in detail.
A car that moves in a linear motion starts to move with an acceleration of 5.6 m / s2, which smoothly drops to zero within 17 seconds while at rest, and continues to move at a constant speed at the end of 17 seconds. How long it takes while the distance is 451 m that has been traveled from the beginning?

You travel from point A to point B in a car moving at a constant speed of 70 km/h. Then you travel the same distance from point B to another point C, moving at a constant speed of 90 km/h. Is your average speed for the entire trip from A to C 80 km/h? Explain why or why not.
A car starts from rest with an acceleration of 5.7 m/s² which decreases linearly with time to zero in 8.2 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 240 m from the start. Answer: t = i 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.

What is the car's average acceleration in ft/s2? b) In 3.5 more seconds, the car is going 84 ft/s (57 mi/h). What is the car's average acceleration for this time period? (c) The car then slows to 63 ft/s (43 mi/h) in 2.5 s. What is the average acceleration for this time period? (d) What is the overall average acceleration for the total time?
A car starts from rest with an acceleration of 7.5 m/s² which decreases linearly with time to zero in 9.9 seconds, after which the car continues at a constant speed. Determine the time t required for the car to travel 520 m from the start. Answer: t = i S
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? (Hint: You can ignore the effects due to gravity
A subway car leaves station A; it gains speed at the rate of 4 ft/s² for 6 s and then at the rate of 6 ft/s² until it has reached the speed of 48 ft/s. The car maintains the same speed until it approaches station B; brakes are then applied, giving the car a constant deceleration and bringing it to a stop in 6 s. The total running time from A to B is 40 s. Determine the distance between stations A and B.
