En el salto vertical, la energía cinética de Francisco se transforma en energía potencial gravitatoria sin la ayuda de una garrocha. ¿Con qué rapidez mínima debe dejar el suelo Francisco, para elevar su centro de masa 2,10 y cruzar la barra con una velocidad de 0,70 ? M

The image shows the positions of a car on a roller coaster track. arrange the cars in order based on their gravitational potential energy. begin with the lowest potential energy and end with the highest.

In science and physics what is the standard unit of measure for speed?

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.
