    Physics question on acceleration and force.?

    A packing crate is placed on a plane inclined at an angle of 35o from horizontal. If the coefficient of static friction between the crate and the plane is 0.65, will the crate slide down the plane? Justify your answer.

    Need help on this PHYSICS question. Please explain as well.?

    A particular spring has a force constant of 2.5 X 103 N/m. (a) How much work is done in stretching the initially-relaxed spring by 6.0 cm? (b) How much more work is done in stretching the spring an additional 2.0 cm? THANKS!!!!

    TOUGH Physics question. Plz help. Really struggling!!! Plz explain too.?

    A student could either pull or push, at an angle of 30o from the horizontal, a 50-kg crate on a horizontal surface, where the coefficient of kinetic friction between the crate and surface is 0.20. The crate is to be moved a horizontal distance of 15 m. (a) Compared with pushing, pulling requires...

    What is the minimum speed a trail bike must be moving to clear the ditch?

    A ditch 2.5 m wide crosses a trail bike path. An upward incline of 15o has been built up on the approach so that the top of the incline is level with the top of the ditch.(Add 1.4 m to the range for the back of the bike to clear the ditch safely.) HOW DID YOU CALCULATE THIS ANSWER?

    ...velocity relative to you? While you are traveling in a car on a straight, level inter-state highway at 90 km/h, another car passes you in the same direction; its speedometer reads 120 km/h. (a) What is your velocity relative to the other driver? (b) What is the other car's velocity relative...
