(22 POINTS) If the equation (d = xv + 1 a y²) describes the motion of a body, where (d) has the dimensional formula of the length, (v) has the dimensional formula of the velocity
and (a) has the dimensional formula of the acceleration.
Find the dimensions of both x and y.

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

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.)
