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))
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.
