Un automovil que viaja al este aumenta su velocidad de 30 km/h a 60 km/h en 4 segundos. Calcula su aceleración.

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

There are weak or strong attractive forces between atoms of liquids with a high viscosity

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
