A boat of mass 250 kg is coasting, with its engine in neutral, through the water at speed 1.00 m/s when it starts to rain with incredible intensity. The rain is falling vertically, and it accumulates in the boat at the rate of 100 kg/hr .

What is the speed of the boat after time 0.500 hr has passed?
Is the component of the total momentum of the system parallel to the direction of motion still conserved?
What is the acceleration of the boat just after the rain starts?

a) , b) Yes, c)

Explanation:

a) A boat travelling in neutral means that boat is not experimenting any force from engine, the equation of equilibrium is:

The following differential equation is constructed:

The speed at t = 0.5 hours is:

b) Since there is no external force exerted on the boat, the component of the total momentum of the system parallel to the direction of motion is conserved.

c) The acceleration of the boat after the rain starts is:

d. learned preferences i believe is your answer

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
