Car A and B start a race from rest. Car A starts with an acceleration of 100 m/s^2 and after 10s increases with acceleration to 200 m/s^2. Car B starts with an acceleration of 50 m/s^2 and after 5s increases the acceleration to 300 m/s^2. 1) What is the distance between cars after 1s 2) What is the velocity of each car after 1s 3) After 30 seconds which car is ahead?

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...

The tangential acceleration of a car that starts from rest at A is (90 + s)/ 450 m/s^2, where s is the distance in meters measured along the curse from A. Compute the acceleration vector of the car when it is at B.

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, 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 train has a length of 104 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 8.14 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 39.9 s, the car is again at the...

A train has a length of 107 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 11.3 s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 37.3 s, the car is again at the...
Consider two toy cars. Car A starts from rest and speeds up with constant acceleration for...
Consider two toy cars. Car A starts from rest and speeds up with constant acceleration for a time tA until it reaches a speed of vA and then continues to travel at this speed. At the moment car A reaches its maximum speed, car B, starting at rest from the same point that car A started from, speeds up with constant acceleration aB. a) Make a freehand plot of the speed of each car as a function of time. Label...

A car is initially at rest on a straight road. The graph shows
the acceleration of the car along that road as a function of
time.
What is the speed of the car at t=7 s?
4.0 m/s
You are correct.
b) What distance does the car cover in the first 8 seconds?
c) What is the speed of the car at t=14 s?
d) Determine the distance covered by the car between t=11 s and
t=13 s?

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) =
The tangential acceleration of a car that starts from rest at A is (90 + s)/ 450 m/s^2, where s is the distance in meters measured along the curse from A. Compute the acceleration vector of the car when it is at B.
