Question

what is the formula for velocity (v^2) in equation of motion ? A. v^2=u+gt B. v^2=ut+1/2gt^2 C. v^2=ut+2gs. D. v^2=u^2+2gs​

Answer 1

Answer:

Answer is Option D as it is the correct and the third equation of motion(for a freely falling body).

Answer 2

Answer:

D)v^2=u^2+2gs

Step-by-step explanation:

we know that,

v^2-u^2=2as

if the acceleration is due to gravity then,

v^2+u^2=2gs

v^2=u^2+2gs

hence it is proved
