Title: How do you find time when only given initial and vertical velocity? Post by: juan123 on May 8, 2013 A projectile is fired at such an angle from the horizontal that the vertical component of its velocity is 49 m/s. The horizontal component of its velocity is 61 m/s. How long does the object remain in the air?
Thanks in advance! Also, since the path of a projectile is like a parabola (not including air resistance), why don't the properties of a parabola work? For example, you can't find time and value of maximum height using properties learned in math. Title: How do you find time when only given initial and vertical velocity? Post by: leemac on May 8, 2013 T = 2*(vy/g)
Flight time = 2*(49/9.8) = 10 s Vx is constant during flight. Maximum height is reached in 5 seconds--> same down. Title: How do you find time when only given initial and vertical velocity? Post by: smiley on May 8, 2013 Content hidden
