3.10. if the position vector of the particle is given by F = 3t²i + 5j + 4k
Find: (a). The velocity of the particle at t = 3 s (b). Speed of the particle
at t=3s (c) acceleration of the particle at time t = 3 s​

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?
