Un proyectil de masa m (kg) se dispara con una velocidad v (m/s) contra un bloque de masa 4m inicialmente en reposo. Tras la colisión el sistema proyectil-bloque sale unido como un único cuerpo que se desplaza por una superficie horizontal y rugosa. Sabiendo que el coeficiente de rozamiento de la superficie es μ, determine la distancia máxima que recorre el cuerpo en función de todos los datos del problema.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
