Answer:
W = 30 N
Explanation:
Applying the summation of torques about the wedge for equilibrium, taking the clockwise direction as negative. Since the ruler is balanced horizontally about the wedge. Therefore, the summation of all torques acting about the wedge must be equal to zero.
<u>W = 30 N</u>
Newtons third law of motion is as below
every action has an equal and opposite reaction
#action=force
#reaction =another force
Forward and downward speed are referred to as acceleration and deceleration respectively.
<h3>
What is Acceleration?</h3>
This is the rate at which an object gains speed with respect to time with its unit being meter per second square(m/s²).
Objects in constant speed are said to have a uniform motion. The downward speed is known as deceleration which involves the object losing speed to return to a state of rest.
