Explanation:
GIVEN DATA:
Engine operating speed nf = 8325 rev/min
engine angular speed ni= 12125 rev/min
motorcycle angular speed N_m= - 4.2 rev/min
ratio of moment of inertia of engine to motorcycle is given as
The answer is A.68 degrees
The answer would be center of mass, B
Answer:
50 N
Explanation:
Let the force in the horizontal rope be F₁ and the force in the diagonal rope be F₂:
The total force in the horizontal and vertical directions must be zero, since the object is at rest and is not accelerating.
The horizontal component of the forces:
F₁ + F₂ = -40N + F₂ = 0
F₂ = 40N
The vertical component of the forces:
F₁ + F₂ - mg = 0 + F₂ - mg = 0
F₂ = mg
If I assume the gravitational constant g = 10 m/s²:
F₂ = (3 kg) * (10 m/s²) = 30N
Adding the horizontal and vertical components of the force F₂:
F₂ = √((40N)² + (30N)²) = 50N
