Hello I am having toruble solving this problem. I would appreciate any help.(adsbygoogle = window.adsbygoogle || []).push({});

A 75 N block is pushed at 5.0 m/s up a ramp 6.0 m long to a platform 2.0 m high. If the coefficient of friction is 0.300

a) how much work was done?

b) how much work was done aginst friction?

c) how much work was done against gravity?

d) how much power was developed?

I solved for theta using trig and got 19 degrees.

Then I solved for work with the equation [Fw(sintheta+ucostheta)]h and got 91J.

I am confused on how to solve for the work against friction and the work aginst gravity though.

Thanks for any help
