A projectile of mass 0.636 kg is shot from a cannon, at height 6.6 m, as shown in the figure, with an initial velocity vi having a horizontal component of 6.8 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

Question

past the end of the cannon’s barrel.Find the magnitude of the velocity vector
when the projectile hits the ground. The
acceleration of gravity is 9.8 ms2. Answer in units of m/s.

Answer 1

7.7 m/s
