Mr. Verma (50 kg) and Mr. mathur (60 kg) are sitting at the two extreames of 4 m long boat (40 kg) standing still in water. to discuss a mechanics problem, they come the middle of the boat . neglecting friction with water, how far does the boat move in the water during the process?
Smooth surface produces ----- friction than a rough surface.
The arrow with a pointed tip can move faster in air than that of with a blunt tip.
State whether the given statement is true or false:
Fluid friction is more than solid friction.
A man of mass $m$ walks from end $A$ to the other end $B$ of a boat of mass $M$ and length $l$. The coefficient of friction between the man and the boat is $ \mu $ and neglect any resistive force between the boat and the water.
