    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    I know you have other people to help. I am sorry I was just hoping to get more clarification. This has me totally lost and so I apologize for taking up your time and still not getting it. Thank you for trying though

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    So with my numbers given of the gun being fired at 4 meters and traveling 98.5 meters am I using the 4 meters? t = Square root 2 (4)m/?

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    I am just not too sure how in the example given they have square root 230m/9.81m/s^2 and that equals 4.84s? How do they get that answer?

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    Are you still there, or totally frustrated with me? I am so sorry I have been working on papers for two days now and I am exhausted and I cannot get the equations to even post correctly

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    So to solve for the elapsed time we solve for t in terms of y so t = Square root -2y/g

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    This was the example given to me, but I see through working through it none of the numbers were used to get 4.84, so how do I start?

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    . A rock is thrown horizontally from a 115 meter vertical cliff. The rock strikes the ground 92.5 meters from the base of the cliff. Determine the speed at which the rock was thrown. Since we know the value of y, we can begin the problem by solving for...

    Calculate Initial Muzzle Velocity for Gun Using Physics Equations

    I know I need to start there, but I guess I am just lost as to how to solve for time. I have the equation, but I just am lost. I have examples in front of me, but I have no idea how they even got some of the numbers I only have the two I gave you
