Homework Statement A hand exerts a constant horizontal force on a block thatis free to slide on a frictionless surface. The block starts fromrest at point A, and by the time it has traveled a distance d topoint B it is traveling with speed Vb. When the block has traveledanother distance d to...

also do you think its has anything to do with my work? or equations?

yeahi tried it in degree mode and i tried just putting it into radian mode and then just converting but i still get the same wrong answer...

thats what i keep saying to myself but my friend said she was able to get the same answer as the one provided in the book...

the secondd equation comes because friction is ignored in this problem so in the equation mg*sin(theta)-(static kinetic energy)*cos(theta) the static kinetic energy doesn't apply so you can think of it as 0... so you're left with mg*sin(theta) and since you need to make sure that the customers...
