A river is to be crossed by a girl using a row boat.
Assume that the water has uniform velocity, represented above by
the vector labeled H. The rowing speed of the girl and a set of
possible orientation of her boat are also shown. Select the
direction (i.e., F, or D, or ...) in order to cross the river in
the shortest time. (Notice that the number of tries is
reduced.)
For which rowing orientation will the girl land...

A 65.0-kg boy and his 40.0-kg sister, both wearing roller blades, face each other at rest. The girl pushes the boy hard, sending him backwards with velocity 2.90 m/s towards the west. Ignore friction. (a) Describe the subsequent motion of the girl. (b) How much potential energy in the girls body is converted into mechanical energy of the boy-girl system? (c) Is the momentum of the boy-girl system conserved in the pushing-apart process? If so, explain how that is possible...

A girl stands on the deck of the boat and tosses a rock into a lake. The rock is thrown from a height of 2.50 m above the water surface with a velocity of 4.35 m/s at an angle of 60.0° above the horizontal. As the rock strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the rock enters the...
