a projectile of mass of .787 kg is shot from a cannon, at height 6.8 m as shown in the figure with an initial velocity vi having a horizontal component of 5.7m/s2.(adsbygoogle = window.adsbygoogle || []).push({});

vix cos53

5.7=.6018150232

9.471348804=vi

viy=sin53 * vi

viy=.79863551*9.471348804

viy=7.564155483

Determine the MAximum height deltay the projectile achieves after leaving the end of the cannon's barrel. answer in units of m/s.

a=9.8

vi=7.564155483

vf=0

vf^2=vi^2 +2as

0=(7.564155483)^2 +2(9.8)s

57.21644817+19.6s

-57.21644817=19.65

s=2.919206539

HELP!!!

Find the magnitude of the velocity vector when the projectile hits the ground. Answer in units of m/s.

Find the magnitude of the angle (with respect to horizontal0 the projectile makes when im pacting the ground. Answer in units of degrees.
