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...

im just confused for the vector notation of direction. i know how to take the equations and solve for what i need. the velocity given in vector noation is throwing me off.

the problem didnt copy right.. 7.1 i + 6.1 j so yes, horizontal is first, vertical is second.

yes.

Homework Statement A ball is shot from the ground into the air. At a height of 8.7 m, its velocity is = 7.1 + 6.1 m/s, with horizontal and upward. (a) To what maximum height does the ball rise? (b) What total horizontal distance does the ball travel? What are the (c) magnitude and (d) angle...

Homework Statement Find the (a) x, (b) y, and (c) z components of the sum of the displacements and whose components (in meters, m) along the three axes are cx = 7.9, cy = -4.0, cz = -6.2; dx = 4.5, dy = -1.5, dz = 3.3. Homework Equations I don't know. The Attempt at a Solution No idea how...
