A boat with a total mass of 500 kg is travelling north on a lake. The motor of the boat provides a force of 400 N in the northerly direction. The wind blows 30◦ away from the northerly direction slightly towards east. It exerts a force of 300 N on the boat. Find the acceleration of the boat including magnitude and direction. Assume that the friction between the boat and the water of the lake is negligible.

A 285-kg stunt boat is driven
on the surface of a lake at a constant speed of 13.5 m/s toward a
ramp, which is angled at 25.4° above the horizontal. The
coefficient of friction between the boat bottom and the ramp's
surface is 0.150, and the raised end of the ramp is 2.10 m above
the water surface.

A barge of mass M = 300 kg is floating on a lake (assume there are no forces between the barge and the water in the plane of the lake and that the water is not moving). The barge is moving at a velocity vo = 0.4 m/s along the +x direction. As the barge floats by, a man of mass m = 90 kg standing at the edge of the lake takes a running start and jumps in the...

8. A water management policy proposal is being discussed by City Z to preserve Lake Pearl in its territory. This policy allows City Z to upgrade its water infrastructure and to establish a water quality monitoring program. The goal is to improve water quality of Lake Pearl from Level II (water quality index=50) to Level I (water quality index=100). 1) A stated preference survey among a sample of residents (100 people out of 10,000 total population in City Z) was...
