A projectile of mass 0.445 kg is shot from a cannon. The end of the cannon's barrel is at height 6.7 m, as shown in the figure.The initial velocity o, of the projectile has a horizontal component of 6.9 m/s.The projectile rises to a maximum height of delta y above the end of the cannon's barrel and strikes the ground a horizontal distance delta x past the end of the cannon's barrel.Determine the time it takes for the projectile to reach its maximum height.The acceleration of gravity is -9.8 m/s^2.Answer in units of s.How long does it take the projectile to hit the ground?Answer in units of s.What is the horizontal range of the shot?Answer in units of m.
