Question

$v_f = v_i + at$ what variable is this equation missing

Explanation:

The equation $v_f = v_i + at$ is a kinematic equation where:

• $v_f$ = final velocity,
• $v_i$ = initial velocity,
• $a$ = acceleration,
• $t$ = time.

Acceleration and final velocity are already represented in the equation, so the missing variable is displacement.

Answer:

displacement
