Question

Un corp se misca uniform accelerat si parcurge intr-un interval de timp $t_1$ distanta $d_1$ si imediat dupa acest interval parcurge distanta $d_2$ intr-un interval de timp $t_2$. Acceleratia corpului este:

a) $\frac{ \frac{d_2}{t_2}- \frac{d_1}{t_1} }{t_1+t_2}$

b) $2\frac{ \frac{d_2}{t_2}- \frac{d_1}{t_1} }{t_1+t_2}$

c) $2\frac{ \frac{d_2}{t_2}- \frac{d_1}{t_1} }{t_1-t_2}$

d) $2( \frac{d_2}{t_2^2} - \frac{d_1}{t_1^2} )$

e) $2 \frac{d_2-d_1}{t_2^2-t_1^2}$

f) $2 \frac{ \frac{d_1}{t_1} + \frac{d_2}{t_2} }{t_1+t_2}$

Answer 1

Primele doua ecuatii sunt Fizica, restul este Matematica!
