Chapter 11, Problem 11.187RP
A roller-coaster car is traveling at a speed of 20 m/s when it passes through point B. At that point, it enters a concave down circular section of the track that has a radius of curvature of 60 m. After it reaches point B, the car’s speed increases at a rate of 4 m/s2. Determine (a) the time it takes the car to reach point D, (b) the x and y components of the overall acceleration of the car when it reaches point D.

A car moved on a horizontal path from rest at constant acceleration from point A until it reached its maximum speed when passing by
At point b it took 4 seconds, and after point B it continued its movement but at a slowdown of -3 m / s2 until it stopped at c
Categorical
The idling distance of 13.5 m. Find:
1. The distance the car traveled while accelerating from a to b
2. The car's rate of acceleration (acceleration)
3. The car's maximum speed from point b
4. The time the car took when slowing down from b to c
At time t = 17 s, the velocity of a particle moving in the x-y plane is v = 0.14i +2.92j m/s. By time t = 17.13 s, its velocity has become
0.01i + 2.82j m/s. Determine the magnitude day of its average acceleration during this interval and the angle made by the average
acceleration with the positive x-axis. The angle is measured counterclockwise from the positive x-axis.

A car is about to pass through an arc bridge, as shown in the figure below. Given that thespeed of the car is 5 m/s constantly, determine the magnitude and direction of the car’s acceleration at thehighest point, B, and at the end of the bridge, point C (assume the car is still on the bridge). For a parabola that has a general equation of (y = ax2 + bx + c) , the x coordinate of the vertex can be found by (-(b/2a))
