A car, starting from rest, accelerates in a straight-line path at a constant rate of 2.0 m/s2. How far will the car travel in 12 seconds?
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 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 cyclist starts from rest and rides in a straight line, increasing speed so that her wheels have a constant angular acceleration of 2.0 rad/s2 around their axles. She accelerates until her wheels are rotating at 8.0 rad/s. If the radius of a tire is 0.31 meters, how far has the cyclist traveled? Answer in m (#10.9.5)
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. The entire trip from start to finish( starting and ending at rest) lasts for a duration of 24.3s. a) what is the duration of...
A particle starts from rest and accelerates uniformly in a straight line. The particle travels a distance of 6.70 m in 2.50 s . How fast, in miles/hour (mph), will the particle be traveling after a time of 4.50 s has elapsed? Assume 1 mile=1609.34 m. Express your answer using three significant figures.
A car starts from rest and moves along a straight line with an acceleration of a =10x(-1/5) m/s where x is in meters. Determine the cars position and velocity when = 4.481 s. X(4.481) V(4.481) =

A car in stop-and-go traffic starts at rest, moves forward 21 m in 8.0 s, then comes to rest again The velocity-versus-time plot for this car is given in the figure (Figure 1). Part A What distance does the car cover in the first 4.0 seconds of its motion? Part B What distance does the car cover in the last 2.0 seconds of its motion? Part C What is the constant speed V that characterizes the middle portion of its...
