Question

A projectile of mass 0.622 kg isshot from a cannon. The end of the cannon’s barrel is at height 6.5m, as shown in the figure. The initial velocity of the projectileis 9.6 m/s .
The projectile rises to a maximum height of y above the end of thecannon’s barrel and
strikes the ground a horizontal distance x past the end of thecannon’s 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 units of s.

c)Find the range x of the projectile.
Answer in units of m.
