    What is the uniqueness of solutions for linear equations at x=0?

    (a)Show that xy' + 2y = 3x has only one solution defined at x=0. Then Show that the initial value problem for this equation with initial condition y(0)= yo has a unique solution when yo = 0 and no solution when y0=/= 0 . (b) Show that xy'-2y=3x has an infinite number of solutions defined at...

    What Determines the Maximum Speed of a Ball Fired from a Toy Cannon?

    A toy cannon uses a spring tp project a 5.3 g soft rubber ball. The spring is originally compressed by 5 cm and has a force constant 8N/m .When the cannon is fired , the ball moves 15cm through the horizontal barrel of the cannon ,and there is a constant friction force of 0.032 N . between the...

    Calculating Friction Force: Static and Kinetic Coefficients Explained

    Response to: force question i don't understand this..the way the forces go if someone could show me how to do it and the steps..that would be great: The static friction coefficient btw a wall and a pic is 0.7 while the kinetic one is 0.3. By what force shoudl one push the 6kg pic against...
