A motorcycle travels an average velocity of 35 km/br. If the cyclist is going to a friend's house 12 km away, how long does it take the cyclist to make the trip?

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
