Homework Help: Projectile motion Problems.

  1. Oct 8, 2006 #1
    Here is a problem about projectile motion. I have the answer but I'm not sure if they are correct or not, please help check. Thanks!

    Problem: Tom the cat is chasing Jerry the mouse across a table surface 1.5m above the floor. Jerry steps out of the way at the last second, and Tom slides off the edge of the table at a speed of 5m/s. Where will Tom strike the floor, and what velocity components will he have just before he hits?

    My Answers:

    used the x= and y= equations, easy.

    Velocity components just before he hits:
    Vxo=5m/s, because no accel. or force. Constant Velocity.
    Vyo=9.8m/s^2 * time???
    so 9.8m/s^2 * .5533s = 5.42234 m/s
    Is that correctly done for the velocity component of Vyo??

    Also, when it says find the velocity components just before he hits, does it mean to find Vxo and Vyo?? Do you need to find the resultant vector also? What I mean is the single vector that is Vxo and Vyo added together. I think the components just mean x and y right?

    That's right.

    ok so I just need the x and y velocity components. ty:tongue:
