Acat jumps off a piano that is 1.3m high. the initial velocity of the cat is 3m/s at an angle of 37degrees above the horizontal. how far from the edge of the piano does the cat strike the floor.

Explanation:

From the exercise we have that

To find how far from the edge of the piano does the cat strike the floor, we need to calculate its time first

At the end of the motion y=0m

Solving for t

or

Since the time can't be negative the answer is t=0.73

Knowing that we can calculate how far does the cat strike the floor

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
