If a car were to start at rest and move along a straight road at a constant acceleration reaching a speed of 14 ms-1 in 4 s, the what would be the magnitude of the constant acceleration of the car? And how fast will the car be travelling if it maintains this acceleration over a distance of 140 m from its starting point?

The driver of a car slams on the brakes when he sees a tree blocking the road. The car slows uniformly with an acceleration of 5.60 m/s2 for 4.20 s, making straight skid marks 62.4 m long, all the way to the tree. With what speed does the car then strike the tree?
If a car were to start at rest and move along a straight road at a constant acceleration reaching a speed of 14 ms-1 in 4 s, the what would be the magnitude of the constant acceleration of the car?
A car comes to a complete stop from an initial speed of 60 mi / hr in a distance of 200 ft. With the same constant acceleration, what would be the stopping distance s from an initial speed of 55 mi / hr?
Two trains travel in the opposite direction, leaving each of the opposite stations which call station A and station B. The train A departs at a constant speed of 150[km/h], while the train B leaves from rest with constant acceleration of 1,5[m/s]. HOW far and at what time do the two trenes intersect? Consider that the two stations are separated by a distance of 10[km].
When are you most aware of motion in a moving vehicle—when it is moving steadily in a straight line or when it is accelerating? If a car moved with absolutely constant velocity (no bumps at all), would you be aware of motion?
A baseball is pitched, reaching the batter with a speed of 37 m/s, and is hit such that it returns on the same line at 48 m/s. If the ball was in contact with the bat for .22 seconds, what was the magnitude of the average acceleration experienced by the ball during the time of contact?
What is the final speed of a bullet train accelerating at the rate of 200km/hr² from initial speed of 150km/hr over a distance of 100km?
A boat is cruising in a straight line at a constant speed of 2.6 m/s when it is shifted into neutral. After coasting 12 m the engine is engaged again, and the boat resumes cruising at the reduced constant speed of 1.6 m/s. Assuming constant acceleration while coasting, how much time did it take for the boat to coast the 12 m?
During a braking test, a car is brought to rest beginning from an initial speed of 54 mi/hr in a distance of 134 ft. With the same constant deceleration, what would be the stopping distance s from an initial speed of 75 mi/hr?
A car is travelling at a constant speed of 100 km.hr at the highway when the driver noticed that the bridge 10 m away is cut off. If the driver immediately applied the brakes upon noticing the cut off bridge, what must be his deceleration so he would not fall to the river?
The driver of a car traveling at 20m/s needs to quickly reduce the car's speed to 15m/s to round a curve in a highway. If the deceleration has a magnitude of 6m/s^2, how far does it travel while reducing the speed?
A cricket player accelerates the ball from a velocity of 5.5 m/s to 39 m/s in one direction. If this shot takes 3.5 × 10-2 s, calculate the distance, in meters, over which the ball accelerates.
