A person jogs 8 complete laps around a 400m track in a total time of 14.5 min. what is the average speed in m/s? what is the average velocity in m/s?

An aquarium 6 m long, 1 m wide, and 1 m deep is full of water. Find the work needed to pump half of the water out of the aquarium. (Use 9.8 m/s2 for g and the fact that the density of water is 1000 kg/m3.)

A 63 kg ice skater finishes her performance and crossed the finish line with a speed of 10.8 m/s. Suppose she accepts a huge 4.4 kg bouquet of flowers. Find her new speed. (Use momentum or impluse formulas from physics)

How long does it take the moon to go from full-moon phase to new-moon phase

What is the rule of calculation of elastic potential energy?

In 1940, the Tacoma Narrows Bridge across the Puget Sound collapsed. The bridge was a suspension bridge. The wind blowing through the narrows matched the natural frequency of the bridge.
