Hello guys! First post here on the forums and I'd greatly appreciate it if I could receive some help with 2 physics questions. The first one is a projectile question, and the second involves and object falling in a certain time frame through a certain length. 1. A car is racing towards a 20 degree inclined ramp at 30m/s. The driver has to TRY and clear a piranha tank and land on an identical ramp on the opposite side. To get vertical component I did cos70=x/30 x=10.26m/s ***That is the vertical speed/component And to get the horizontal speed/component I did Pythagoras theorem, I ended up getting 28.2m/s. I know then you have to sub it into the quadratic equation but im never given the height of the ramp, other than knowing that I will need to land on an identical ramp on the other side. So do I just sub in 0 for the "c" part? So -10.26 +/- SQR -10.26^-4(-4.9)(0)/2(-4.9) and then get time and then sub it into the horizontal speed/component and get the distance covered? Second question An object falls past a 1.9m window in 0.2s. Determine the height of the object above the window. I know this is wrong but what I tried to do was determine the velocity (9.5m/s) and I'm GUESSING that the distance above the window is 9.5m? Help would be greatly appreciated.
