Pre-Calculus Vectors Word Problem?
Hi everyone, if you can help me with this problem relating to vectors, it would be great. The book I have is absolutely horrific and provides no examples. Just a cheap attempt by the authors to rip off the educational system for some quick cash.
Enough of the rant. Here’s the problem:
Billy and Timmy are using a ramp to load furniture into a truck. While rolling a 250-pound piano up the ramp, they discover that the truck is too full of other furniture for the piano to fit. Timmy holds the piano in place on the ramp while Billy repositions other items to make room for it in the truck. If the angle of inclination of the ramp is 20 degrees, how many pounds of force must Timmy exert to hold the piano in position?
Thank you so much!

Good luck!
