The x-component is related with the Force through the trigonometric function cosine.
cos(42°) = x-component / F ⇒ x-component = Fcos(42°) = 112N*0.743 = 83.2 N
The correct formula for calculating the tangential speed of an orbiting object is V(t)=wr.
V(t)= Tangential Speed
w= Angular Velocity
r= Radius of the Path
Hope this helps.
Answer:
37.5 N Hard
Explanation:
Hook's law: The force applied to an elastic material is directly proportional to the extension provided the elastic limit of the material is not exceeded.
Using the expression for hook's law,
F = ke.............. Equation 1
F = Force of the athlete, k = force constant of the spring, e = extension/compression of the spring.
Given: k = 750 N/m, e = 5.0 cm = 0.05 m
Substitute into equation 1
F = 750(0.05)
F = 37.5 N
Hence the athlete is pushing 37.5 N hard
100cm to go in 600 secs = 10mins
2 positive, 1 negative .... net 1 positive per step
Hi, thank you for posting your question here at Brainly. I hope I would be able to answer your question.
From the problem statement, it is mentioned that Chip based it from human behavior as a result of the unconscious minds. Hence, the approach Chip used is Psychodynamic/Psychanalysis, which deals with the reasoning of human behavior by studying his past experiences that may have made a significant imprint on his unconscious mind.
