The horizontal component of the force is the product of the cosine of the angle and the magnitude of the force, Fx = (73.8 N)(cos 39) = 57.35 N. The vertical component of this force is the product of the sine of the angle and the force, Fy = (73.8 N)(sin 39) = 46.44 N.
Answer:
<h2>117.6 J</h2>
Explanation:
The gravitational potential energy of a body can be found by using the formula
GPE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
GPE = 6 × 9.8 × 2
We have the final answer as
<h3>117.6 J</h3>
Hope this helps you
Answer:
Zero
Explanation:
As we know that the force and the motion direction should always be perpendicular to each other due to which the work is done by static friction be zero
Therefore
F.dcos(theta) = F.d cos(90) = 0
Hence, the work done by static friction is zero
Therefore the same is to be considered
The other two bulbs stay lit with the same brightness.
