A cannon sends a projectile towards a target a distance 1210 m away. The initial velocity makes an angle 26o with the horizontal. The target is hit. The acceleration of gravity is 9.8 m/s2 . What is the magnitude of the initial velocity? Answer in units of m/s y = viy•t +0.5•ay•t2 vix =...

Thank you! you are right I don't know much about vectors. That is so simple, I thought that somehow the x and y-axis information might have to be combined but then if I only used one is seemed like I would leave out half of the velocity; but using the information of one axis independent of the...

thanks for the response, here is kinda what I have done so far ahh...attempts! I have tried to solve this several ways with multiple answers and still i get it wrong. 1st I tried to solve for v;v=at, using 3m/s2i as accel-->then used v/time to get distance and add to x to get , wrong. I...

A particle moves in the xy plane with constant acceleration. At time zero, the particle is at x = 5.5 m, y = 2.5 m, and has velocity ṽ=(2.5 m/s) î+ (−2 m/s)ĵ . The acceleration is given by ā =(3 m/s2) î+ (7.5 m/s2)ĵ. What is the x component of velocity after 2.5 s? Answer in units...
