A boat is travelling along a circular path having a radius of 30 m. Determine the magnitude of boat's acceleration, a, when the speed is 5.7 m/s and the rate of increase in the speed is 7.5 m/s² Enter a1: m/s2 Enter a : m/s²

The motion of the collar at "A" is controlled by a motor at "B" such that when the collar is at SA = 3 ft it is moving upwards at 4 ft/s and is slowing down at 2 ft/s². Determine the velocity and acceleration of a point on the cable as it is being drawn into the motor "B" at this instant. 4 ft SA T A BO Ans. aB = 3.248 ft/s² 1

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 the image below, what is the rotation of rod AB about point A if piston b moves to the right? Moreover, what is the magnitude of the acceleration of end a if velocity of end A is 7.5 m/s upward and is increasing at a constate rate of 18.75 m/s^2?
