At a county fair, two children ram each other head-on while riding on the bumper cars. Jill and her car, traveling left at 3.10m/s, have a total mass of 330kg. Jack and his car, traveling to the right at 1.80m/s, have a total mass of 255kg.
1. Assuming the collision to be elastic, decide the speed of Jill and her car after the collision.
2. Decide the speed of Jack and his car after the collision.
The two cylinders both have a radius of 1mm. Material 1 has a conductivity of 1.2 x10^4 S/m and material 2 has a conductivity of 1.4 x 10^4 S/m. Piece 1 is 6cm long and piece 2 is 8cm long.
Two 29.0%u2212cm -focal-length converging lenses are placed 14.0cm apart. An object is placed 39.0cm in front of one lens. Where will the final image formed by the second lens be located
In designing rotating space stations to provide for artificial-gravity environments, one of the constraints that must be considered is motion sickness. Studies have shown that the negative effects of motion sickness begin to appear when the rotati..
