1. The problem statement, all variables and given/known data my friend is standing on the roof of my house trying to fix the satellite. Suppose he needs a wrench and asked me to toss one up to him. If i stand 20.0m away and toss the wrench to the top of the 10.0m tall building, what is the magnitude of the velocity with which I need to throw the wrench? 2. Relevant equations Kinematic Equations. 3. The attempt at a solution Vox = ? Vx = ? ax = 0 T = ? Distance in x direction = 20 Voy = ? Vy = ? ax = -9.9 T = ? Distance in the y direction = -10 I got a hint that said two kinematic equations need to be set equal to each other to solve for time and initial Vx velocity, but i have no idea how to set that up... Exam tomorrow... please help!!
