A 33-kg projectile is launched straight up with a speed of 85 m/sec.
A)What is its initial kinetic energy?
B) How High will it go, if we assume there is no air resistance/
C) Actually, air resistance was significant, and the projectile only goes 328 meters high. What percentage of the initial energy of the projectile was "stolen" by air resistance, ending up as heat? answer in %

A projectile is launched straight up from ground level with an initial velocity of v0 per sec. Neglecting air resistance, its height in feet, s, after t seconds after launch is given by the equation s = –16t2 + v0t. At what time(s) will the projectile reach a height of 112 feet when v0 = 96 feet/sec? After how many seconds will it return to the ground when v0 = 96 feet/sec?
