A 4.97-g bullet is shot through a1.02-kg wood block suspended on a string2.00 m long. The center of mass of the block rises a distance of0.49 cm. Find the speed of the bullet asit emerges from the block if its initial speed is 404 m/s.
The sun is in the sky at an angle of 22 degrees from vertical. You’ve built a column exactly 12.0 meters in height. You stand on the ground at the end of the column’s shadow. (THIS is where the concepts of sin, cos, and tan originally came from.....)..
After falling from rest from a height of 33 m, a 0.47-kg ball rebounds upward, reaching a height of 23 m. what average force was exerted on the ball
An air-filled capacitor consists of two parallel plates, each with an area of 7.60 cm2, separated by a distance of1.70 mm. What is the surface charge density? What is the capacitance?
An object with a mass of m = 4.8 kg is attached to the free end of a light string wrapped around a reel of radius R = 0.235 m and mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a vertical plane about the horizontal axis passing t..
An unknown gas is introduced into the aforementioned apparatus using the same tuning fork, and the first resonance occurs when the air column is 6.14 cm long. Find the speed of sound in the gas. m/s
