Projectile motion question (horizontal distance)

[From: ] [author: ] [Date: 11-12-07] [Hit: ]
must be solved in terms of time, then applied to horiz. vector to find distance traveled.-if the projectile lands at the same level it was launched,v0 is the launch velocity, theta is the launch angle,......
If you have the-
angle
mass
velocity
acceleration

what is the equation to find the total horizontal distance?
thanx

See may answer to your previous question which I think you just missed!

-
Start with velocity and elevation, COS elevation = horiz. vector, SIN elevation = vert. vector. If ballistic then Vert vector is diminished by 32 ft/s/s till stop, then reverse till grounded, must be solved in terms of time, then applied to horiz. vector to find distance traveled.

if the projectile lands at the same level it was launched,

range = v0^2 sin(2 theta)/g

v0 is the launch velocity, theta is the launch angle, g is the accel due to gravity
