please give a thumps up.
4. The is -(0. t 3 s bucket is hoisted by the rope that wraps around a drum wheel. If the angular displacement of the wheel 5t +15t) rad, where t is in seconds, determine the velocity and acceleration of the bucket when 0.75 ft
A wheel with radius 0.50 meters starts rotating at a constant angular acceleration of 0.5 rad/s^2. a) What is the angular velocity of the wheel after 15 seconds? b) The angle through which the wheel rotates during this time? c) The number of revolutions made by the wheel during this time? d) What is the linear velocity of the wheel after 20 seconds? e) What is linear acceleration of the wheel after 20 seconds? omega = omega_0 + alpha t...
Thanks so much ahead of time! A spherical shell of radius 0.43 m and mass 27 kg initially rolls without slipping towards an incline at a linear speed of 9.1 m/s. If the ball rolls up an incline (inclined 35 degrees above the horizontal) without sliding. How high will it go? A professor holding a spinning wheel used for a demonstration brings the wheel to a stop by applying a constant, tangential friction force to the edge (his hand). The...
Q2. The rod OB in Figure Q2 is rotating anticlockwise around O with an angular velocity of 2trad/s. Collar A moves along the rod with speed t sin(2t) m/s 8Orad and r-1m when t 0 s. a) Calculate the magnitude of the velocity vector of the collar A relative to o at t 1s. 5 Marks] b) Calculate the acceleration vector of the collar A relative to O at t-1s.
