Physics
A ball is launched with a velocity of 10 m/s at an angle of 50.0 degrees to the horizontal. The launch point is at the base of a ramp of horizontal length 6.00 m and 3.60 m high. A plateau is located at the top of the ramp. a) Does the ball land on the ramp or plateau? Justify...

Physics (Rolling)
In Fig. 11-35, a solid brass ball of mass m will roll smoothly along a loop-the-loop track when released from rest along the straight section. The circular loop has radius R, and the ball has radius r << R. (a) What is h if the ball is on the verge of leaving the track ...

Physics
A mass sits at the top of a 2 meter long ramp inclined at an angle of 30 degrees (to the horizontal). When the mass is released, it slides down the ramp and then onto a level floor. If both the ramp and the board have a coefficient of .25 (Friction), how far out onto the floor...
