Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Can someone please help me to fully solve all of the following questions.
A ship heading due west @ 1.5 m/s meets a current going South east at 1m/s. Find the resultant speed and direction of the ship. At the same time, a crew member climbs the ship's mast at 0.7m/s, find the magnitude and direction of the crew member travelling through space: draw the space and vector diagrams to accompany both answers. not sure if this example I have is acceptable or if the answer is right. I'm struggling to understand all the vectors and units. So better space and vector diagrams and a break down of the formulas and units would be great thanks

y x = r cos 0 V = Or y = r sine r = √x² + y² χ Flow in "solid body rotation" acts like a solid spinning around an axis. The streamlines are circular, the velocity is purely tangential, and the velocity magnitude is V = r, where is the angular velocity (positive counter-clockwise) and r is the radius. (a) Express the velocity vector V as a function of x and y. (b) Calculate the curl of the velocity vector V × V, indicating clearly the direction of the resulting vector.

You are surfing, but the waves are lame so you paddle back to shore. The waves are pushing you directly to the shore, but you are paddling at an angle, so that you get closer to where you parked your car. The waves are pushing you 10 ft/sec, and you are paddling 45◦ to the right at a speed of 5 ft/sec.(a) Draw a to scale vector diagram of this situation. Your diagram should include the vector describing the velocity from the waves, and the vector describing the velocity from your paddling. Label the scale of your drawing.(b) On your drawing above, use the two given vectors to make a scale draw- ing of their resultant vector. Then use the scale of your drawing to estimate the magnitude of the resultant. Show the calculation of using the scale.
