Document Summary
All answers must include the correct plus or minus sign and the correct units. (14 pts) i. A small rock is thrown from the edge of the roof of a building with an initial velocity that has magnitude v0 = 1 8. 0 rn/s and a direction of 0 3 6. 9 above the horizontal. The rock hits the ground a horizontal distance of 50. 0 m from where it was thrown. A box of mass 5. 00 kg moves on a ramp that is inclined at 36. 9 above the horizontal. A person is applying a constant force f 70. 0 n to the box. The direction of f is parallel to the ramp and directed up the ramp. A block of mass 5. 00 kg is placed against a horizontal spring that is compressed. The spring is released and the block moves along a horizontal surface, leaving the spring behind. The coefficient of kinetic friction between the block and the surface lspk = 0. 300.
