Att = 0, a projectile is located at the origin and has a velocity of 20 m/s at 40° above the horizontal. The profile of the surface the projectile strikes can be approximated by the equation y = 0.4x -0.006x² where x and y are in maters. (a) Determine the x and y coordinates of the post where the projectile hits the ground in meters. (b) Determine the time the projectile hits the ground surface in sec. (c) Determine the velocity of the projectile when it hits the ground surface in m/s.

Question
Transcribed Image Text:Att = 0, a projectile is located at the origin and has a velocity of 20 m/s at 40° above the horizontal. The
profile of the surface the projectile strikes can be approximated by the equation y = 0.4x -0.006x² where
x and y are in maters. (a) Determine the x and y coordinates of the post where the projectile hits the
ground in meters. (b) Determine the time the projectile hits the ground surface in sec. (c) Determine the
velocity of the projectile when it hits the ground surface in m/s.
