A 25.9 kg projectile is launched vertically with an initial velocity of 130. m/s. For times t = 0.00 s, t = 5.00 s, and t = 20.0 s, find the following quantities: (a) The velocity at all times (b) The position at all times (c) The kinetic energy at all times (d) The gravitational potential energy at all times (e) The total mechanical energy at all times

The image below shows the motion of several distance stars relative to an observer. The arrows indicate the star’s direction of motion, and the longer the arrow, the faster a star’s motion. Rank these stars in order from the greatest “blueshift” to the greatest “redshift”. Note: If a star would exhibit no shift, then it should go between those with blueshift and those with redshift.
