Kinetic energy is stored energy that is released, for example, a fast-moving roller coaster down a slope. Potential energy is energy that has stored energy, for example, a stretched rubber band.
Answer:
Answer:
118.4 N
Explanation:
weight of chair, mg = 95 N
Push, F = 39 N
Ф = 37 ° below x axis
Let n be the normal force.
So, by using the diagram and resolve the components of Force F.
n = mg + F SinФ
n = 95 + 39 Sin 37°
n = 95 + 39 x 0.6
n = 118.4 N
Explanation:
If the answer is not C D then is A bc of the way it crosses over
