Three balls are launched from the same point high on a cliff - they all end up landing at different places on the flat ground below. the launch point is 30.0 m above the ground, and all the balls are launched with the same speed of 28.0 m/s. ball a is launched with an initial velocity that is entirely horizontal. ball b's initial velocity is directed at an angle of 43.0 degrees above the horizontal. ball c's initial velocity is directed at an angle of 22.0 degrees below the horizontal. as usual, we will neglect air resistance. use g = 9.80 \; m/s^2. rank the balls based on the speed they each have just before impact with the ground, from largest to smallest.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
