Question

Herb’s bank balance is $1793. He deposits $375 and then $418. a. How much does he have in his account now ? (1) b. If he then withdraws $895 to buy a kite-surfing kit, how much will be left in his acc

Answer 1

Answer:

Step-by-step explanation:

• Though they may appear similar, these two sports have entirely different origins, and hence are entirely different beasts:
• Windsurfing has surfing and sailing as its progenitors.
• Kitesurfing has beach kiting and wakeboarding as its progenitors.
• If you look at the picture comparing a windsurfer to a surfer, the ancestry becomes abundantly clear. In the picture, the sail is no longer used for propulsion, just for balance. The steering dynamics are virtually the same (i.e. weight pressure shifting). Windsurfing is truly “wind surfing”. By the way, windsurfing was invented by surfers who no longer wanted to depend on a motor tow to get out on the big swells.
• Alternatively, compare a kitesurfer to a wakeboarder, and again the similarity is striking. Basically, the motorboat has been replace with a kite. It also suggests that “kiteboarding” would be a more appropriate name than “kitesurfing”.
• All this means propulsion (a sail as opposed to a kite) and navigation (a volume as opposed to a board) are entirely different, requiring different skills.
• In my view, there are a few points that make kitesurfing (much) easier to learn than windsurfing:
• You can acquire almost all required skills on dry land. It is perfectly possible to learn to control a kite on the beach (remember, beach kiting is one of kite surfing’s progenitors);
• Just like a motorboat, the power of the kite remains readily available to assist you with fall recovery, since the kite (through basic, beach-learned skills) remains up in the air all the time.
• No tacking or jibing (changing the board side your heels are on) is required on bi-directional boards (which make up the proverbial 99% of kiteboards).
• The base technique remains basically the same throughout all levels (just like in snowboarding).
• aerobatics (“jumping” etc.) are surprisingly easy, as they merely require powering up the kite. They are not so much difficult than dangerous (kite out of control, beach crash etc.)
• Windsurfing scores quite the opposite across the board (no pun intended):
• It can only be learned on the water. That means a tricky and tiring process of fall & recovery (up-hauling the sail), before managing even a single run.
• Recovery in high winds can only happen through an advanced technique called a water start. It can take several seasons before you’re even ready to learn how to water start (which in itself may take yet another season). If you don’t know how to water start, you shouldn’t go out in heavy winds, which means you cannot learn how to water start, which means … It requires considerable risk-taking (with luckily only risk to yourself) to break this Catch-22 (read, going out in heavy winds when you don’t know how to get on the board again!)
• You have to change board sides all the time (remember, sailing is windsurfing’s other parent). In light winds, this is typically done through tacking, but in high winds, the “easiest” procedure is a power jibe, a high-speed, sail wielding maneuver that again requires multiple seasons to master, through a seemingly endless series of fall & recoveries in high winds. You can really only call yourself an accomplished windsurfer if you have mastered both the water start and the power jibe (inevitably, in that order).
• Half-way the learning cycle there’s a complete paradigm shift in technique: you start using the harness and foot straps, which in turn will allow you to get the board into planing mode. It’s only here that the real fun begins. But not before having been violently catapulted a couple of times trying. You could compare the intensity of change to evolving from stem christie skiing to parallel skiing.
• aerobatics are the reserve of semi-professionals and beyond. Anywhere below that level and you will be lucky to even get the board off the water…
• The above has some safety consequences, brought about by the difference in learning curve steepness;
