Aball of mass 3.0 kg is tied to the end of a 75-cm length of string. the ball and string are swung in a circle in a vertical plane at constant speed v, which is the minimum speed necessary to keep the string taut at all times. the center of the circle is above the floor. suddenly, the string is released at the instant the ball is at point p, located half way from the top to bottom on the descending arc. after what span of time does the ball hit the floor?

Aparticle moves in the xy plane with constant acceleration. at time zero, the particle is at x = 6 m, y = 8.5 m, and has velocity ~vo = (9 m/s) ˆı + (−2.5 m/s) ˆ . the acceleration is given by ~a = (4.5 m/s 2 ) ˆı + (3 m/s 2 ) ˆ . what is the x component of velocity after 3.5 s? answer in units of m/s.
