The car is traveling at a speed of 60 mi/hr as it approaches point A. Beginning at A, the car decelerates at a constant 6.3 ft/sec? until it gets to point B, after which its constant rate of decrease of speed is 2.7 ft/sec? as it rounds the interchange ramp. Determine the magnitude of the total car acceleration (a) just before it gets to B, (b) just after it passes B, and (c) at point C.

An object is thrown from a level field with initial upward speed 17 m/s and forward speed 9.9 m/s. How far (in m) from its launch point is its landing place? You do not need to put the unit in the answer, just the number. As usual, ignore air resistance, etc; use the acceleration due to gravity as 9.8 meters per second squared.
Car A is parked along the northbound lane of a highway, and car B is traveling in the southbound lane at a constant speed of 60 mi/h. At t=0, A starts and accelerates at a constant rate a A , while at t= 5 s, B begins to slow down with a constant deceleration of magnitude a A 6. Knowing that when the cars pass each other x = 294 ft and VA = VB , determine (a) the acceleration aA,(b) when the vehicles pass each other, (c) the distance d between the vehicles at t=0.
A typical jetliner lands at a speed of 160 mi/h and decelerates at the rate of (10.0 mi/h)/s. If the plane travels at a constant speed of 160 mi/h for 1.00 s after landing before applying the brakes, what is the total displacement of the aircraft between touchdown on the runway and coming to rest?
Suppose a car merges into freeway traffic on a 200 -m-long ramp. If its initial velocity is 10 m/s and it accelerates at 2 m/s2, how long does it take to travel the 200 m up the ramp? (Such information might be useful to a traffic engineer.) v0=__m/s
(a) Can the equations in Table 2.4 be used in a situation where the acceleration varies with time? (b) Can they be used when the acceleration is zero?

A car travels in the +x-direction on a straight and level road. For the first 4.00 s of its motion, the average velocity of the car is V(av-x) = 6.25 m/s. How far does the car travel in 4.00s?
A car is traveling at 96 km/h when the driver sees an accident 75 m ahead and slams on the brakes. What minimum constant deceleration (in m/s2) is required to stop the car in time to avoid a multi-car pileup? (Round your answer to two decimal places.)
A jet plane comes in for a landing with a speed of 100 m/s, and its acceleration can have a maximum magnitude of 5.00 m/s^2 as it comes to rest, from the instant the plane touches the runway, what is the minimum time interval needed before it can come to rest?
A car is moving in constant motion along the positive x-direction on a straight and level road. For the first 4.0 seconds of its motion, the average velocity of the car is vav-x = 8 m/s. How far did the car travel in the first 3.0 seconds?
An ambulance driver is rushing a patient to the hospital. While traveling at 71.1 km/h, she notices the traffic light at the upcoming intersection has turned yellow. To reach the intersection before the light turns red, she must travel 52 m in 2.17 seconds. What is the magnitude of the minimum acceleration, in m/s2, required to reach the intersection before the light turns red?
A driver applies the brakes on his car reducing its speed from 31.0 m/s to 11.0 m/s in a time 5.0 secs while traveling a distance of 121 m. What is that magnitude of the car's average acceleration during the 5.0 sec period?
If the car’s speed decreases at a constant rate from 70 mi/hmi/h to 40 mi/hmi/h in 3.0 ss, what is the magnitude of its acceleration, assuming that it continues to move in a straight line? What distance does the car travel during the braking period?
