PLS HELP I'LL MARK BRAINLIEST The figure shows four forces exerted on a box.

A square is shown with an arrow pointing up labeled F3, an arrow pointing right labeled F1, an arrow pointing down labeled F4 and an arrow pointing left labeled F2

If F1 is equal to F2 and F4 is greater than F3, which statement is correct? (3 points)

a
An unbalanced force will move the box up.

b
An unbalanced force will move the box down.

c
Several balanced forces will keep the box stationary.

d
Several balanced forces will keep the box moving towards the right.

In which of the following cases is work being done on an object? question 2 options: pushing against a locked door carrying a box down a corridor pulling a trailer up a hill suspending a heavy weight with a strong chain

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.
