Problem 57 Hard Difficulty

$\bullet$ Look out! A snowball rolls off a barn roof that slopes downward at an angle
of $40.0^{\circ} .$ (See Figure $3.42 . )$ The edge of the roof is 14.0 $\mathrm{m}$ Ignore air resistance. How far from the edge of the barn does the snowball strike the ground if it doesn't strike anything else while falling?

Answer

6.91 $\mathrm{m}$

so far. This problem take plus y Toby down and extra bit towards light. So we have a X monstrous ego. Hey, why is positive 9.8 meters per second. Now that acceleration is downward on DH. A lot of positive lines also in the downward direction. So we don't need toe. Put the ticket of sign before this. Fine. We're not exes. Do not cause I noted another tea. Don't notice the angle. Uh, a sub 10 days at the horizontal. This is called a 5.36 meters per second. Similarly v not Why is we know time. Sign off. Three cannot. This is acquittal 4.5 meters per second. Now we use the vertical motion to find the time in the air. Andrea will use this equation which is perfect for cut out the clothes. And this value is 40 meter. They're not. Why is 4.5 meters per second on behalf ofthe? This acceleration is 4.9 meters a second scratch. Now this is a tragically question on this caves A to be equal to one whole wood twice off for a fun night times negative 4.5. That's minus 4.5 square minus four times 4.9 times negative. What thing on the units is in seconds. Now, let me just drive the general for mulatto Solve the quantity question. So if you have prided Dicky question off this phone and you want to solve for X, which is being in your in your question so extra be called negative. Off B Less minus the squared. Minus four time. Save time. See over two a. Now for this, a question. If you take this 14 meter, do the other side in simple words. If you take all these variables to one side and keep the other side to be called consider Oh, you see that? This is you know, a It is for fine nine 4.5 is there will be on DH C will be negative off 40 meters. My That's why there is a negative sign here. Now, if we solve this for time on the negative value over here if you think if we take the negative sign and solve this we will get the negative and knew for time that is not physical on. Therefore, we should ignore it on just solve the secretion from the positive sign on the positive route is equaled one point nine seconds. Now we can find X minus X not which is equal to be not Eckstein Stateless half X t squared. But since excess Edo the stone just goes on way left with we not we not extend sti and this is equal to six point nine.
