Q1. A dental bracket exerts the horizontal force of 80.0 N on a tooth at point B. What is the torque on the root of tooth about point A?

Q2. A pinball spring with a k value of 79.2 N/m is compressed a distance of 3.5 cm. If it launches a pinball at a speed of 1.4 m/s, what is the mass of the pinball?

Q3. One side of the roof of a building slopes up at 34.0°. A student throws a Frisbee onto the roof. It strikes with a speed of 15.0 m/s and does not bounce, but slides straight up incline. The coefficient of kinetic friction between plastic and roof is 0.410. The Frisbee slides 10.0 m up the roof to its peak, where it goes into free fall, following a parabolic trajectory with negligible air resistance.

Conclude the maximum height the Frisbee reaches above the point where it struck roof.
