If a projectile launches from and lands at the ground, and has a HANGTIME of 4 seconds, what is its VERTICAL velocity when it hits the ground? (use -10 m/s2 for gravity concept)
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
True/False Vertical and horizontal velocities are independent of each other for a projectile.
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
If we know both vertical and horizontal velocity components for a projectile, what trig function do we use to find the launch angle?
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
If we know the initial velocity and launch angle, what trig function would we use to find the vertical velocity component?
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
What angle could you launch a projectile with that would give you the same distance (range) as one launched at 30 degrees? Neglect air resistance.
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
Which velocity component remains constant for the path of a projectile?
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
What launch angle would give the greatest height for a projectile, if all initial velocities were equal?
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
If one bullet is dropped at the same moment and the same height as another bullet that is fired horizontally from a gun, which one hits the ground first?
90 degrees
tangent
True
sine
-20 m/s
60 degrees
horizontal velocity
they both hit the ground at the same time
