Assume the hz amp pendulum is 12 m long and that the bowling ball has a mass of 7 kg. you pull the bowling ball to the right by 5 m of arc length and release it. using the "small angle approximation" and treating the resulting motion as simple harmonic motion, what is the kinetic energy of the ball when it swings through its original resting position in j?

For general projectile motion, when the projectile is at the highest point of its trajectory, its acceleration is zero? a)the horizontal and vertical components of its velocity are zero. b) its velocity is perpendicular to the acceleration. c)the horizontal component of its velocity is zero. d)its velocity and acceleration are both zero.
