A car traveling at 18 {rm m/s} runs out of gas while traveling up a 24.0^circ slope. How far up the hill will it coast before starting to roll back down.
You are working out on a rowing machine. Each time you pull the rowing bar (which simulates the "oars") toward you, compute the magnitude of the force that you exert on the handle
Protons are projected with an initial velocity v0 = 10360 m/s into a region where a uniform electric field E = 670 N/C is present. The protons are to hit a target that lies a horizontal distance of 1.27 mm from the point where protons are launched..
