Kramer goes bowling and decides to employ the force of gravity to "pick up a spare." He rolls the 6.50 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.245 m from the one remaining 2.00 kg bowling pin.
Treat both the ball and the pin as point objects, and determine the magnitude of the force of gravity ?⃗ grav between them.
Riders in an amusement park ride shaped like a Viking ship hung from a large pivot are rotated back and forth like a rigid pendulum. Sometime near the middle of the ride, the ship is momentarily motionless at the top of its circular arc. The ship then swings down under the influence of gravity.
(a)
Assuming negligible friction, find the speed (in m/s) of the riders at the bottom of its arc, given the system's center of mass travels in an arc having a radius of 16.0 m and the riders are near the center of mass. (Assume the top of the circular arc is when the pendulum arm is horizontal. You may need to use energy methods from the next chapter.)
(b)
What is the centripetal acceleration (in m/s2) at the bottom of the arc?
