    Work done using time, velocity and mass?

    If you assume a constant deceleration, you can use constant acceleration equations such as x = 1/2(vo + v)*t and v = vo + a*t. Work = Fd, where F is the force and d is the displacement. This can be expanded to W = m*a*d. Using the acceleration equations, you should be able to find all of your...

    Projectile Motion - Two fired at different times

    I replaced them, but I am a little confused (I don't know why I can't get this as it seems simple). From the first equation I got \frac{v_{01}cos(\theta_1)t}{v_{02}cos(\theta_2)} = t - T I then put this into the 2nd equation and got v_{01}sin(\theta_1)t =...

    Projectile Motion - Two fired at different times

    Should my left side then be t^2-T^2?

    Projectile Motion - Two fired at different times

    t-T Would I then find t and T from x and plug that into z?

    Projectile Motion - Two fired at different times

    Homework Statement Two projectiles are fired, one at t = 0 with velocity v01, making an angle θ1 with x-axis, and the other at t = T > 0 with velocity v02 making an angle θ2 with x-axis. Show that if they are to collide in midair the travel interval T between the two firings must be...

    What is Engineering Physics?

    Hi there everyone! I am Aubrey Hughes. I am an engineering student at the University of Saskatchewan. Trying to get my bachelor's in Engineering Physics. Thanks for all the help so far! (thought I should finally become a member lol)
