If an object is dropped from a tall building and it hits the ground 3.0 s later, what is the velocity of the object when it hits the ground? (remember that the velocity is downward)
v= m/s

-29.4 m/s

Explanation:

Initial velocity is 0 m/s.

Acceleration is -9.8 m/s².

Time is 3.0 s.

v = at + v₀

v = (-9.8)(3.0) + 0

v = -29.4 m/s

i guess the game developers wanted to give off a more gamey/cartoony feeling without trying to copy fortnite exactly

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
