A particle slides back and forth on a frictionless track whose height as a function of horizontal position x is given by y = ax2, where a = 0.94 m-1.
If the particle's maximum speed is 8.9 m/s, determine the turning points of its motion.
While the dried up seed pod of a scotch broom plant bursts open, it shoots out a seed with an initial velocity of 2.4 m/s at an angle of 60° above the horizontal.
A 3.00-kg object is fastened to a light spring, with the intervening cord passing over a pulley. The pulley is frictionless, and its inertia may be neglected.
