21. A boat has a maximum speed of 5.0 m/s in still water. The boat heads East across a 300 m river that flows South at 2.5 m/s.
a. Find the time it takes to cross the river
b. Find the distance the boat travels downstream
c. Find the resultant velocity

Anybody wanna ? (picture included? )

Which graph represents motion with an object with positive velocity that is located at a position of 3 meters at a time of 0 seconds? a) a b) bb eliminate c) c d) d

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.
