Now, to get numerical equations for x and y, you’ll need to know the initial values (at time t = 0) for some velocities and accelerations. On the Table below the video:
Select cm as the mass measurement set to display.
Click the Table label and check all x and y displacement and velocity data: x, y, vx, and vy. Then click Close.
Now rewrite the displacement equations from Part A and Part B above by substituting in the x and y velocity values from time t = 0 and also using the theoretical value of acceleration of gravity. Write them out below.

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
