1. Does anybody know how to do this problem? I really dont know how to even start.

A block slides down an inclined plane 9m long that makes an angle of 38 degrees with the horizontal. The coefficient of sliding friction is 0.25 If the block starts from rest, find the time required for it to reach the foot of the plane

.........

4. i think you need to work out the vertical or horizontal component or both and throw in 9.8 somewhere

5. you missed anything?

6. thats all the info i got, im thinking that its impossible to do

7. nothing from a previous question?

8. no this is the only problem the teacher gave us

9. wow
make me feel dumb.I dont even know 5x6 and thats no joke :<

10. The coefficient of sliding friction is 0.25 If the block starts from rest

i dont get it. if this is supposed to multiply or something it never moves

*goes to find what coefficiant means*

11. if 0.25 means metres per second it takes 36 seconds. but it cant be, otherwise it wouldn't state starting from rest. maybe if there was more info i could work out the acceleration.
