A ball on the end of a string is whirled around in a horizontal circle of radius 0.300 m. The plane of the circle is 1.10 m above the ground. The string breaks and the ball lands 2.40 m (horizontally) away from the point on the ground directly beneath the ball's location when the string breaks. Find the radial acceleration of the ball during its circular motion.

At one instant a bicyclist is 49.0 m due east of a park's flagpole, going due south with a speed of 14m/s. Then 35.0 s later, the cyclist is 49.0 m due north of the flagpole, going due east with a speed of 14m/s.
Now suppose that the two masses continue to move at the speed from Part A until they encounter a rough surface. The coefficient of friction between the masses and the surface is . If the blocks come to rest after a distance, which of following equ..
Suppose the region outside the chamber is evacuated and the total mass of the block and the movable piston is150 kg. What is the distance s through which the piston rises
