Cal Liber shoots a bullet through a huge pile of watermelon. The bullet enters the pile at 210 m/s and it takes the bullet 0.27 s to get through the pile. If the bullet slows down
at a rate of 661 m/s2. how wide was the pile of watermelon?

The crank oa rotates in the vertical plane with a constant clockwise angular velocity ω0 of 5.6 rad/s. for the position where oa is horizontal, calculate the force under the light roller b of the 10.6-kg slender bar ab.

Asystematic approach to problem solving is called a (an)

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?
