Answer:
Angular velocity = 0.105 rads⁻¹
speed of tip = 0.00105 ms⁻¹
Explanation:
A second hand turns 2π rad each 60 sec
Thus: it has an angular speed given by
ω = 2π/T = 2π/60 = π/30 = 0.105 rad s⁻¹
The speed of the tip is given by
V= rω = 0.01 m × (0.105 rads⁻¹)
= 0.00105 ms⁻¹
Answer:
the angular acceleration of the gate is approximately 1.61
Explanation:
Recall the formula that connects the net torque with the moment of inertia of a rotating object about its axis of rotation, and the angular acceleration (similar to Newton's second law with net force, mass, and linear acceleration):
In our case, both forces contribute to the same direction of torque, so we can add their torques up and get the net torque on the gate:
Now we use this value to obtain the angular acceleration by using the given moment of inertia of the rotating gate:
