Physics work and energy problems
WebbWork = Force × Distance × cos θ. Put in the values we know: Work = 200 N × 3 m × cos 20°. Work = 200 N × 3 m × 0.9397... Work = 564 N m (to nearest N m) 1 N m is 1 Joule (J) the … WebbWork and Energy Problems – Their Solutions 1. A block slides down a curved frictionless tract and then up an incline. The coefficient of kinetic friction between the block and the incline is µk. Using energy methods show that the maximum height reached by the block h is ymax = . 1 + µ k cot θ
