Answer: a
Explanation: because the answer is 1.4444444 and that's the closest
Answer:
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
Explanation:
They indicate that the angular velocity is constant, that is
w = dθ / dt
Where θ is the radius swept angle and t the time taken.
The tangential velocity is linear or
v = dx / dt
Where x is the distance traveled in time (t)
In the definition of radians
θ = s / R
Where s is the arc traveled and R the radius vector from the pivot point, if the angle is small the arc (s) and the length (x) are almost equal
θ = x / R
We substitute in the speed equation
v = d (θ R) / dt
The radius is a constant for each point
v = R dθ / dt
v = R w
With this expression we see that for each point at different radius the tangential velocity is different
Answer:
The force of gravity effected by stream the was muscle in the earth.
Explanation:
It just was
The blue car is moving with a velocity of -14 m/s using the red car as a reference frame.
N=m.g
N=72 x 9.8 = 705.6 ≈ 706 N
