Question

A projectile of mass 0.796 kg is shot from

a cannon. The end of the cannon

A projectile of mass 0.796 kg is shot from a cannon. The end of the cannon's barrel is at height 6.2 m, as shown in the ?gure. The initial velocity vi of the projectile has a horizontal component of 7.6 m/s. The projectile rises to a maximum height of ?y above the end of the cannon's barrel and strikes the ground a horizontal distance ?x past the end of the cannon's barrel. 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. How long does it take the projectile to hit the ground? Answer in units of s. Find the range x of the projectile. Answer in units of m.

Explanation / Answer

procedure is

initial horizontal component speed: Vox = 6.4 m/s
? = 56
