(NEED IMMEDIATE HELP/OFFERING 20 POINTS) You use a wedge that has a width of 1.1 in and a slope length of 3.3 in. What is the mechanical advantage of this wedge?

A. 2.2

B. 3

C. 4.5

D. 0.33

B. 3

Explanation:

The ideal mechanical advantage of a wedge is determined by dividing the length of the wedge by its width.

Therefore, our required result is obtain as thus:

Mechanical advantage = length / width

= 3.3 / 1.1 = 3

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
