Work done by a constant force!!! A small plane tows a glider at constant speed and altitude. If the plane does 2.00 X 10^5 J of work to tow the glider 145m and the tension in the tow rope is 2560N, what is the angle between the tow rope and the horizontal? This is one of my homework problems. I think that I might be using the wrong formula for this. What formula should I use? And If its possible could someone please show me how to solve this step by step I really want to understand this stuff, so any and all help would be greatly appreciated!!!
