Homework Statement
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?
Homework Equations
Kinematic Equations.
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!
