Micah rows his boat on a river 4. 48 miles downstream, with the current, in 0. 32 hours. He rows back upstream the same distance, against the current, in 0. 56 hours. Assuming his rowing speed and the speed of the current are constant, what is the speed of the current?.

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.
