Of course! F=ma, so a=Fnet/m. Fx=mgcos45, and since the force of friction is equal to the coefficient of friction times the normal force (which is equal to Fy and also Fx in this case, since we're dealing with a 45-45-90 right triangle) it ends up equaling mgcos45 (the normal force) times the...
Hello, everyone. I'm new here at the forums, and I've got a little physics problem I'd like your input on:
"A roller coaster reaches the top of the steepest hill with a speed of 6.0 km/h. It then descends the hill, which is at an average angle of 45 degrees and is 45 m long. What will...
