How do I find the Initial Velocity and Time of travel of a clay ball launched from a catapult?

I will be given the Angle of Launch, and the Distance it traveled...How do I find the initial velocity and Time of travel?



Thanks!How do I find the Initial Velocity and Time of travel of a clay ball launched from a catapult?I assume that your catapult is located at the same elevation as the target. Thus the method to do this is to search for the Range equation. It was derived from ballistic motion kinematics principles. It relates angle of launch, and initial speed to the distance traveled.



When you want to find the duration, use t = d/(v0*cos(theta)), also derived from the ballistic motion kinematics equations.How do I find the Initial Velocity and Time of travel of a clay ball launched from a catapult?For the initial velocity, you can use the range equation:



v initial = square root of ((g x distance traveled)/sin(2 x angle))



from the initial velocity, you can find the x component of the velocity by using the cosine function and the original angle. Once you have the x component of the velocity, you can find the time with



v = x/t since velocity in the x direction is constant for a projectile.
