Aprojectile is launched at an angle above the
ground. the horizontal component of the
projectile’s velocity, vx, is initially 40. meters per
second. the vertical component of the projectile’s
velocity, vy, is initially 30. meters per second.
what are the components of the projectile’s
velocity after 2.0 seconds of flight? [neglect
friction.]
(1) vx = 40. m/s and v
y = 10. m/s
(2) vx = 40. m/s and v
y = 30. m/s
(3) vx = 20. m/s and v
y = 10. m/s
(4) vx = 20. m/s and v
y = 30. m/s
