so that is the solution that i tried Variables: ∆dx=2.1 m ∆t=1.1 s V_ix= ? V_iy= ? V_fy= ? a_y= ? ∆dy=0.0275 m V_ix= ∆dx⁄∆t V_ix= (2.1 m)⁄(1.1 s) ∴V_ix= 1.9 m⁄s V_iy= V_ix tan⁡〖70°〗...

i think i am suppose to find the final and initial velocity of the y component i think i also need to find the maximum height of the y component and i don't know which equations to use

sorry for that gneill but all what i need to find is the deltaYd and the Vyf and initial too but the problem this is my first time doing the catapult thingy and the problem is that i have a weak understanding of physics that is why i don't know how to approach this problem

Hi Guys hope u r feeling good i just finished my catapult project and the problem is that i have only two given and the problem is that i have only two given values the \Delta T = 1.1 sec.\Delta_{d}x=2.2 m , and the angle is 70' degrees. and nothing else. http://tinypic.com/r/2ylqpux/7 i...
