Best ResponseYou've already chosen the best response.1From a hilltop to the west of Willy, Oompa Loompas launch gum balls out of slingshots toward his canoe. These gum balls travel in a linear path, dropping 3.2 meters as they travel eastward 15.3 meters to strike the canoe. 1. What's the distance from the Oompa Loompas to the canoe? 2. What is the angle, measured from the horizon, that the Oompa Loompas are firing from? 3. Is it possible for a sling sot propelled gumball to travel in a linear path? If not, what is the flaw in this logic?

Best ResponseYou've already chosen the best response.0I am not very good in English, but if your pic is correct, you found the distance right.

Best ResponseYou've already chosen the best response.1Whoops, no. I ment the law of sines.

Best ResponseYou've already chosen the best response.0\(\theta\) on the @Jonask 's pic is not measured from the horizon.

Best ResponseYou've already chosen the best response.0No matter which angle you search, the law of sines is a ratio, it is mainly used to to find specific sides, but in such a rightangled triangle, as it seems (only judging by the picture  I haven't fully read the problem) you wouldn't want to use that law, more likely the regular trigonometric functions and solve for the angle.

Best ResponseYou've already chosen the best response.1I wonder if it is a right triangle, from part 4.

Best ResponseYou've already chosen the best response.11st of all, is the pic 100% correct?

Best ResponseYou've already chosen the best response.1I really think the drawing is right. I really think the distance is right I do not know about part two, how to get the angle And I am unsure about the logic part 4.

Best ResponseYou've already chosen the best response.1not theta but alpha\[\tan \alpha=3.2/15.3\]

Jonask

Best ResponseYou've already chosen the best response.1now to get alpha use arctan(0.00365)

Best ResponseYou've already chosen the best response.1first of all gravity wont allow the ball just to down at the same angle without pulling it towards the earth 2nd air resistance especially because the horizontal distance is too big compared to the vertical

Best ResponseYou've already chosen the best response.1I was thinking the same, had it wrote down. Wanted to verify. Thanks SOO much.

Best ResponseYou've already chosen the best response.1So what needed to be done to find the angle from the horizon?

Jonask

Best ResponseYou've already chosen the best response.1its that arctan 0.00365=0.209 degrees this also accounts for the balls imppsossible perpetual linear motion
