A spring has a force constant of 100 N/m and an unstretched length of .07 m. One end is attached to a post that is free to rotate in the center of a smooth table. The other end is attached to a 1 kg disc moving in uniform circular motion on the table, which stretches the spring by .03 m. Friction is negligible. What is the centripetal force on the disc? A. .3 N B. 3N C. 10 N D. 300 N E. 1,000 N
Boat A negotiates a curve whose radius is 370 m. Boat B negotiates a curve whose radius is 120 m. Each boat experiences the similar centripetal acceleration. What is the ratio of speed of boat A to that of boat B.
assume that for the couple in, you were told that the girl's mass was two-thirds that of the boy. The boy has a velocity of v = +0.61 m/s. What would be the girl's velocity in this case.
The proper length of one spaceship is 2.8 times that of another. The two spaceships are travelling in the same direction and, while both are passing overhead, an Earth observer measures the two spaceships to be the same length.
A 310 kg weather rocket is loaded with 100 kg of fuel and fired straight up. It accelerates upward at 28.0 m/s2 for 32.0 s, and then runs out of fuel. Overlook any air resistance effects.
