A car starts from rest, then accelerates at a constant rate over a distance of 54 m. It then immediately decelerates at a constant rate over a distance of 103 m. The entire trip lasts a total duration of 12.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?
A car starts from rest, and begins accelerating at a constant rate a1. It accelerates at this rate from a distance of 56.9 m from its starting point, and then immediately begins to decelerate at a different constant rate a2, eventually coming to rest again after traveling an additional distance of 79.4 m from where it began decelerating. the entire tripfrom start to finish(starting and ending at rest) lasts for a duration of 19.1 s. a)what is the magnitude of...
A car starts from rest, then accelerates at a constant rate over a distance of 69 m. It then immediately decelerates at a constant rate over a distance of 133 m. The entire trip lasts a total duration of 25.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively? a) 0.61 m/s^2, then 0.61 m/s^2 b) 5.18 m/s^2, then 2.68 m/s^2 c) 1.79 m/s^2, then 0.93 m/s^2 d) 2.68 m/s^2, then 5.18...
A car starts from rest, and begins accelerating at a constant rate a1. It accelerates at this rate for a distance of 57.8m from its starting point, and then immediately begins to decelerate at a different constant rate a2, eventually coming to rest again after traveling an additional distance of 73.8m from where it began decelerating.

A car on a straight level road, starts from rest and accelerates to a speed of 1,846 ft/'s in 49 seconds. What is the car's average acceleration in ft/s??
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
A car accelerates from rest at S m/s for 5 seconds. It moves with a constant velocity for 15 seconds, and then decelerates at 5 m/s to come to rest in 5 seconds. The entire journey takes 25 seconds. Plot the velocity-time graph of the motion AND determine the total distance the car travelled. (10 pts.) 4.
A ride-sharing car moving along a straight section of road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 32.0 m/s. Then the vehicle moves for 41.0 s at constant speed until the brakes are applied, stopping the vehicle in a uniform manner in an additional 5.00 s. (a) How long is the ride-sharing car in motion (in s)? 62 (b) What is the average velocity of the ride-sharing car for the motion described? (Enter the...
A speedboat starts from rest and accelerates at m/s2 for s. At the end of this time, the boat continues for an additional s with acceleration m/s2. Following this, the boat accelerates at m/s2 for s. All the time the boat moved along a straight path. (a) What is the boat's speed at the end of its path? (b) Find the total displacement of the boat. 2.01 We were unable to transcribe this imageWe were unable to transcribe this image0.44...
