- A shot putter exerts a force of 100N acting forward and upward on a 40N shot put at an angle of 60° from horizontal. Other than gravity, the weight of the shot put (40N) is the only external force acting on it.
a. What was the vertical component of this force?
b. What is the horizontal component of this force?
c. How big was the NET force (sum of all external forces) acting on the shot put? (remember gravity is also acting in the horizontal direction)
Homework Answers
a)
Fx = 100 cos 60 = 50 N
b)
Fy = 100 sin 60 = 86.6 N
c)net vertical force
Fv = 86.6 - 40 = 46.6 N
net force
F^2 = Fv^2 + Fx^2
F = 68.3505 N

The same person walking takes a longer stride. He still exerts a downward and forward force of 180 pounds but now at an angle of -45 degrees (315 degrees) to the ground. Resolve the forces into their perpendicular (vertical) and parallel (horizontal) components and label each component also calculate the magnitude of the component forces using trigonometric functions. Show ALL of your work use appropriate symbols.

A gymnast weighing 750 N executes the iron cross. The ring exerts an upward force on the arm of 375 N. The force exerted by the shoulder joint is R, while the muscles exert a total force of M on the arm. M acts at an angle of 45 degrees below the horizontal at a distance of 4 cm from the shoulder joint. The distance from the shoulder joint to ring is 70 cm. Ignore the weight of the arm....
