Trigonometric Ratios
Looking for help with your Physics homework? We're building a collection of example homework problems with detailed solutions to help you get through your high school or college Physics class. We strive to post a new problem every Thursday.
Wally Saves Tammy from the Well
Oh no! Tammy (20 kg) has fallen into the well at the top of the hill. Wally (45 kg) stands near the top of the frictionless slope, which is at a 35° incline to the horizontal. A rope runs over a frictionless pulley to the bottom of the well.
Wally Goes Skiing on a Windy Day
Wally (45 kg), is going skiing. He skis down a frictionless slope that is at a 15° incline from horizontal. A modest wind pushes him from behind with a force of 50 N.
