[Phys-l] A Mechanics Question



A physics instructor sets the following problem.

1) specify how this question is misleading.
2) How could the question be rectified?

The question:

"Billy decides to launch his frisbee over his house. Unfortunately,
his poor aim causes the frisbee to slide up the roof before
continuing past the house.
"Using the data given
[Diagram showing launch height 1 m: launch angle 45 deg:
initial velocity 30 m/s: launch distance to near wall 15m.:
house height to eaves 9 m.: roof height 3 m. roof angle 30 deg.
mu (kinetic) = 0.2 ]

...determine how far the frisbee lands from Billy's feet."


Brian Whatcott Altus OK Eureka!
