Un guepardo parte del reposo y persigue en línea recta a su presa, alcanzando una aceleración constante de 4 m/s2.a)Escribir las ecuaciones horarias. b)Realizar una tabla de valores de v-t, x-t, a-tc. Hacer los gráficos x(t), v(t) y a(t).

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?
