Answer:
Step-by-step explanation:
We have,
Initial velocity of arm club is 23 m/s
Acceleration is 100000 m/s²
It is required to find the time taken by it to take the arm-club to get to 23 m/s. It means v = -23 m/s. It is based on the equation of kinematics such that :
So, the time taken by it is .
Given
the lengths of the 3 sides of a triangle
Find
the angle opposite the longest side
Solution
Strategy: make use of the Law of Cosines, which relates an angle and the three sides of a triangle.
... a² = b² + c² -2bc·cos(A)
... cos(A) = (b² + c² - a²)/(2bc) . . . . . . . solve for cos(A)
... A = arccos((b² + c² - a²)/(2bc))
Fill in the given values and evaluate.
... A = arccos((55² + 50² - 90²)/(2·55·50)) = arccos(-2575/5500)
... A ≈ 117.9°
