    Analyzing the Motion of a Thrown Box Using Newton's Laws of Motion

    Here is the question A quarterback claims that he can throw the football a horizontal distance of 183 m (200 yd). Furthermore, he claims that he can do this by launching the ball at the relatively low angle of 35° above the horizontal. To evaluate his claim, determine the speed with which...

    Analyzing the Motion of a Thrown Box Using Newton's Laws of Motion

    HOLY CRAP it was right! Wow. Thanks so much. I really appreciate it guys. Can I ask a projectile motion question here if I show you guys all the work I have tried?

    Analyzing the Motion of a Thrown Box Using Newton's Laws of Motion

    Then I get it to equal -34558.823 ... there is NO way that can be right right? I was using that v=v(o) + at for the equation... am i even close to on the right track or no?

    Analyzing the Motion of a Thrown Box Using Newton's Laws of Motion

    It's definitely 6.8 milliseconds Well I did make a drawing but how would I post it here? I mean it was just a box that I labeled 41-kg, with a vector towards the wall labeling the direction and velocity(235m/s), and then hitting a wall. Then I had t=6.8ms on the side I am terrible at the...

    Analyzing the Motion of a Thrown Box Using Newton's Laws of Motion

    Homework Statement A 41-kg box is thrown at a speed of 235 m/s and is brought to a halt in a collision that lasts for a time of 6.8 ms. What is the magnitude of the average net force that acts on the box during the collision? Homework Equations Sum of Forces = m*a The Attempt...

    Moment-Generating Functions for Z = 1/4(X-3)

    Homework Statement Given moment-generation function Msubx(t) = e^(3t+8t^2) find the moment-generating function of the random variable Z = 1/4(X-3) and use it to determine the mean and the variance of Z Homework Equations The Attempt at a Solution Honetly I have no idea where...
