A cannonball is fired horizontally (launch angle (1) of 0°) from a height h above the ground, as in the image to the right. The launch velocity is vo, and we are only considering acceleration due to gravity. Show your work as you determine analytical (that is, symbolically in terms of variables and constants) equations for: (a) h the time At before the cannonball hits the ground, in terms of h, vo, and the acceleration due to gravity the distance x that the object travels horizontally before hitting the ground, in terms of h, vo, and the acceleration due to gravity the launch velocity vo, in terms of x, h, and the acceleration due to gravity (b) (c)

Two dogs, Ajax and Bandit, are pulling a Radio Flyer wagon carrying their best cat friend, Casper. the overhead view of the dog force vectors is shown to scale in the grid at the right. (Assume 4 significant figures.) a. Find the single force that is equivalent to the two forces shown. b. If that old rusty wagon DOES NOT MOVE, find the force (including direction) that the ground exerts on the wagon to keep it in place, in spite of the dogs. The forces are measured in units of newtons (N). (You may use EITHER geometry OR vector addition with Cartesian or polarcoordinates. Either way, a diagram to scale is required. Be sure to JUSTIFY whyyour answer to part b is the opposite of your answer to part a.)

what is the answer for the first question part a and b

For part A (and B i guess) what is the starting equation.  Like how did you get uI1I2/(2pi r)?
