Adragster in a race accelerated from stop to 60 m/s by the time it reached the finish line. the dragster moved in a straight line and traveled from the starting line to the finish line at 8.0 m/s2. how long did it take the dragster?

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?
