Acrane winch is lifting a 2300-kg mass. the winch can be modeled as a cable of negligible mass wound around a solid uniform cylinder with a 12-cm radius and a mass of 320 kg that rotates around its central axis. how much torque is required to accelerate the 2300-kg mass straight upward at 0.35 m/s2? assume there is no friction in the system and that the winch radius remains constant

An experiment is designed to test the relationship between the initial height of a basketball before it is dropped to the height of its rebound bounce. the height of the rebound bounce is measured using a scale positioned behind the ball. in the above experiment, which condition would not be controlled? a). the starting height of the ballb). the surface the ball bounces on c). the type of ball d). the method to measure the rebound height of the ball

The table below shows the acceleration of gravity on different bodies in the solar system. on which body would a 10 kg lamp has the most gravitational potential energy when lifted to a height of 2 m? a. earth b. mars c. neptune d. uranus

The material that keeps its new shape after it is stretched is called?
