A projectile of mass 0.213 kg is shot from a cannon. The end of the cannon’s barrel is at height 6.5 m, as shown in the figure. The initial velocity vi of the projectile has a horizontal component of 7.5 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 barrelDetermine the time it takes for the pro- jectile to reach its maximum height. The acceleration of gravity is 9.8 m/s2 .
Answer in units of s.
part 2 How long does it take the projectile to hit the ground?
