a projectile of mass 0.212kg is shot from a cannon. The end of the cannon barrel is at height 6.4m, the initial velocity of the projectile is 9.3m/s. the projectile rises to a max height of y above the end of the cannon%u2019s barrel and strikes the ground a horizontal distance x past the end of the cannon%u2019s barrel.
A) Find the time it takes for the projectile to reach its maximum height. The acceleration of gravity is 9.8 m/s2 . Answer in units of s
B) How long does it take the projectile to hit the ground? answer in seconds
c) Find the range x of the projectile? answer in m
