You want to swim straight across a river that is 76 m wide. You find that you can do this if you swim at an angle of θ = 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ = 0° while directly across the river is θ = 90°).
Q6. A river flows due south with a speed of 6.00 m/s. You steer a motorboat across the river; your velocity relative to the water is 4.00 m/s due east. The river is 500 m wide. (a) What is your velocity (magnitude and direction) relative to the earth? (b) How far south of your starting point will you reach the opposite bank? (c) At what angle from the river flow direction you should steer your boat in order to reach...

As shown in the figure below, a box of mass m = 60.0 kg (initially at rest) is pushed a distance d = 53.0 m across a rough warehouse floor by an applied force of FA - 248 N directed at an angle of 30.0° below the horizontal. The coefficient of kinetic friction between the floor and the box is 0.100. Determine the following. (For parts (a) through (d), give your answer to the nearest...

A block of mass m = 3.5 kg is
on an inclined plane with a coefficient of friction
μ1 = 0.31, at an
initial height h = 0.53 m above
the ground. The plane is inclined at an angle θ =
54°. The block is then compressed against
a spring a distance Δx = 0.11 m
from its equilibrium point (the spring has a spring constant of
k1 = 39 N/m) and
released. At the bottom of the inclined plane...
