thanks so much for your help!

I find the time of the bagels to drop, which was 3.16secs. I used the equation t=sqrt((2Y_0)/g)) = sqrt((2*48.8)/9.8) = 3.16 secs Then since we know the time that it took Henrietta to walk down 4.5 secs + 3.16 secs(the time it took the bagels to drop) now equals to 7.66 secs X= X_o+V_ox*t...

So when t= 0 secs, Henrietta is 18.9m away from the house. So we have to find what time she catches the bagels to find the additional distance that she is away from the house?

I don't know?? 0m?? I mean if I using the correct equation wouldn't it be zero because we are assuming that t= 0 X= 0+(4.2)(0) X= 0? Is this correct?

If I were to plug t = 0, wouldn't it make the answer equal to 0 then?? Am I using the right equations for this problem? Because these are the only equations that my teacher gave me. X= 4.2(0)= 0m Y=Yo + Voy*t - (1/2)(g)(t^2) -48.8= 0 + 0(Voy) - (1/2)(9.8)(0^2) -48.8= ? I don't know...

Homework Statement Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 4.20m/s . Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 48.8m above...

I have no idea what it is asking for? I tried the second case of your idea and it wasn't right also. Do you know if the equation that I used was correct?

Homework Statement It is common to see birds of prey rising upward on thermals. The paths they take may be spiral-like. You can model the spiral motion as uniform circular motion combined with a constant upward velocity. Assume a bird completes a circle of radius 8.00 every 5.00 and rises...

Homework Statement A sailboard is sailing at 6.5 when a gust of wind hits, causing it to accelerate at 0.48 at a 35 angle to its original direction of motion. If the acceleration lasts 6.3 , what is the board's net displacement during the wind gust? Homework Equations Ok so...
