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?
A truck and a car travel on a straight road with equal speeds of 72km / h, when the car is 5 m behind the truck it begins to accelerate at a rate of 2.5m / s ^ 2 until it is 55 meters in front of the truck. the maximum speed reached by the car was 90 km / h, determine the minimum time that the operation takes
Cite an instance in which your speed could be zero while your acceleration is nonzero.
The driver of a car traveling at 110km/h slams on the brakes so that the car undergoes a constant acceleration, skidding to a complete stop at 4.5s . What is the average acceleration of the car during braking?
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?
) A car is moving on a straight road and going at 20 mi/h. Then the driver hitsabruptly the breaks and the car undergoes a motion of constant negative accelerationuntil it stops. We ignore any air-resistance and assume that the car slows down in themost efficient possible way. It comes at a full stop after going a distance of 6.0 m.How much time would it take for the car to stop if instead the initial speed was 45 mi/hand driver hit the breaks as abruptly as in the first case?a. 1.5 sb. 3.0 sc. 1.4 sd. 0.85 s
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].
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?
A locomotive, which accelerates steadily, travels past two consecutive onekilometerstones at speeds of 21 km/h and 29 km/h. What will its speed be at the next stone? (The solution is 35 km/h)
A car is travelling at a constant speed of 100 km.hr at NLEX 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?
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?
