Step 1: Look in your book or online for the conical pendulum equation.
Step 2: Look at the drawing and see which angle is involved in the equation.
Answer: It's Angle #2 in your drawing.
a nonmetal with the amount of valence electrons that will complete atom
Answer:
the force exerted on the foot by the tibia would be 2975 N
Explanation:
Given the data in the question;
To maintain equilibrium between the foot and the ball vertically, the addition normal normal force
(750 N) and the tension in the Achilles tendon
(2225 N) must be equal to the force exerted on the foot by the tibia;
so
|
| + |
| = |
|
so force exerted on the foot by the tibia will be;
|
| = |
| + |
|
so we substitute IN OUR VALUES
|
| = 750 N + 2225 N
|
| = 2975 N
Therefore, the force exerted on the foot by the tibia would be 2975 N
120/60= 2m per s
220/55= 4m per s
720/80= 9m per s
Fastest run: 3rd run
Speed: 9m per s
Slowest: 1st run
Speed: 2m per s
