    Calorimetry A thirsty nurse cools a 2.40 L

    Homework Statement A thirsty nurse cools a 2.40 L bottle of a soft drink (mostly water) by pouring it into a large aluminum mug of mass 0.250 kg and adding 0.123 kg of ice initially at -15.5 degree celsius . If the soft drink and mug are initially at 20.2 degree celsius, what is the final...

    Projectile Motion So many Unknowns

    Woops, yeah I did. vy= v0y - gt Vy=12.31 -9.8(1.9) Vfy=6.31m/s

    Vy^2=Voy^2+2at Vy^2=12.31^2+2(9.8)(1.9) Vfy=13.7m/s

    is it 12.31m/s 5.7=Voy (1.9) - .5(9.8)(1.9^2) 5.7=Voy (1.9) - (17.689) 23.389/1.9=Voy

    y=VoyT-.5*gt^2 but I do not know the vertical displacement

    Sweet. ok anyways vy = v0sinθ-at

    Ok x component No air resistance. The initial velocity will be the same as the final velocity. And there is no acceleration. So as I previously stated Vfx=Vox. Does this mean the Vox=15.8 because displacement=VoxT. So Vx=15.8 and Vox= 15.8

    I know they need to be broken up into two components. There is just not enough information to go from here X: Vox-?, Vfx-? total distance 30 m vx = v0x, x = v0xt, Y: Voy-?, Vfy-?, Vy at point B-Zero, Point B-?, Point C- 5.7m vy= v0y - gt, y = v0yt - (1/2)gt2. Time 1.9sec

    Actually Never mind about the angle. I know that is completely wrong for this kind of problem.

    Projectile Motion So many Unknowns

    Homework Statement Need Help I have been trying to solve this problem for a while now. I know the quadratic formula has to be used in order to solve this problem but I am having trouble getting started. Question A soccer ball is kicked from the ground level at an angle, such that the wall is...
