Inelastic collisions in one dimension: A 2.00-kg object traveling east at 20.0 m/s collides with a 3.00-kg object traveling west at 10.0 m/s. After the collision, the 2.00-kg object has a velocity 5.00 m/s to the west. How much kinetic energy was lost during the collision?

Tensile stress and strain: A 0.600-mm diameter wire stretches 0.500% of its length when it is stretched with a tension of 20.0 N. What is the Young’s modulus of this wire?

What is the correct p-value for the previous problem?

Kepler’s laws: Neptune circles the Sun at a distance of 4.50 × 1012 m once every 164 years. Saturn circles the Sun at a distance of 1.43 × 1012 m. What is the orbital period of Saturn?

Which of the following “t statements” is the proper way to present data in an manuscript using APA format?

Shear stress and strain: The base of an aluminum block, which is fixed in place, measures 90 cm by 90 cm, and the height of the block is 60 cm. A force, applied to the upper face and parallel to it, produces a shear strain of 0.0060. The shear modulus of aluminum is 3.0 × 1010 N/m2. What is the displacement of the upper face in the direction of the applied force?

What we have learned about anger is that ultimately, forgiveness is essential because unresolved feelings of anger only control the person who harbors them.

Sound: What characteristic of sound determines the “pitch” of a musical note?
