The discussion centers on calculating the final velocity of a supersonic jet accelerating uniformly at 23.7 m/s for 20 seconds, starting from an initial velocity of 160 m/s. The correct formula to use is derived from the definition of acceleration, expressed as a = (vf - vi)/t. By rearranging this equation, the final velocity (vf) can be calculated as vf = vi + at, leading to a definitive solution for the problem.
PREREQUISITESStudents studying physics, particularly those focusing on kinematics, as well as educators looking for clear explanations of motion equations.
Since you don't have distance, that won't help. But what's the most basic definition of acceleration?weesieman said:V(final) = V(initial)^2 +2ad. Well that's what I tried using but we just started this topic and I am not sure at all.
Good. Express that mathematically.weesieman said:The rate that velocity changes
That's velocity. What about acceleration?weesieman said:v=d/t
Good! a = (vf - vi)/t.weesieman said:oh right I think i got it. vf-vi/t
