    Projectile motion vector problem

    x is motion on the axis from west to east and y is motion on the axis from south to north, the acceleration in the y direction is that because the only force acting on it is the gravitational force

    Projectile motion vector problem

    Homework Statement At what compensatory angle north of east should a drone, that can only move forward at a maximum speed of 20 m/s, be launched if it is to strike a target that is 400m due east if there is a wind moving 5 m/s south?Homework Equations vx=20cos\Theta vy=20sin\Theta vf2=vi2+2ad...

    Fluid mechanics density problem

    Homework Statement If the density of iron is 7.8x103kg/m3, what is the highest possible height of a square based column of sides=40cm and mass of 1,000kg?Homework Equations \rho=m/v Fg=\rhovg (I think?)The Attempt at a Solution I took the length of the side of the square and used it to find a...

    Time at which a projectile reaches a certain height

    find out it's maximum height and the time it reaches it. from there you can add or subract time to find when it's 10m high

    Distance Traveled Homework: Solve Problem w/ 15° & 100mph

    usually when doing problems like this, the easiest way for me is to write out two columns of kinematic variables (for x and y) so I would have something that looks like X d= a= t= v initial= v final= v...
