Title: In a projectile motion situation where an object is launched at a 45º angle, if x is the horizontal direct? Post by: LERATO on Nov 2, 2012 In a projectile motion situation where an object is launched at a 45º angle, if x is the horizontal direction and drag is neglected, what is the acceleration of the object in the x direction a few seconds after being launched?
Title: In a projectile motion situation where an object is launched at a 45º angle, if x is the horizontal direct? Post by: smokeypal23 on Nov 2, 2012 Zero, gravity works vertically (and down), that is in the negative y direction. Gravity does not act horizontally, or in x.

Post by: dauterjudy938 on Nov 2, 2012 The HORIZONTAL component of the velocity will remain constant throughout the flight. And since the velocity is constant, then its acceleration is zero.
Hope this helps. |
