A block of ice with mass 3 kg slides 0.80m down an inclined plane that slopes downward at an angle of 30 degree below the horizontal. If the block of ice starts from rest, what is its final speed?
You can ignore friction.

THis is your homework assignment. What did you get and how did you get there. Post that and then someone will tell you if you got it right.

What does a block of ice have to do with Tarzan, and Jane?

What does a block of ice have to do with Tarzan, and Jane?Some weird kink? How would Tarzan and Jane get and keep ice...they lived in a tropical jungle and didn't have electricity.

Maybe you need some computer science classes. Read your heading and your question.
Then realize we don't do homework for you-either Tarzan or ice.

Hint: draw a free body diagram of the block, with force components acting in the direction along the vine and perpendicular to it. From F=ma you can get the acceleration down the incline, then apply one of the equations of motion - there's one that relates acceleration and distance travelled to velocity. Post back with your answer and we'll check it for you.
