Una bicicleta parte del reposo con una aceleración de 2m/s². Cuando ha recorrido 100 metros. Mantiene la velocidad constante durante 150 metro. Luego de lo cual frena a razon de 2m/s² hasta detenerse por completo Cual es la distancia total recorrida y en que tiempo?

The system is released from rest with the cable taut, and the homogeneous cylinder does not slip on the rough incline. determine the angular acceleration of the cylinder and the minimum coeffi cient s of friction for which the cylinder will not slip.

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

The energy equivalent of the rest mass of an electron is
