Detailed explanation-1: -Final Velocity Formula vf=vi+at. For a given initial velocity of an object, you can multiply the acceleration due to a force by the time the force is applied and add it to the initial velocity to get the final velocity.
Detailed explanation-2: -Work out which of the displacement ( s ), initial velocity ( u ), acceleration ( a ), and time ( t ) you have to solve for final velocity ( v ). If you have u, a, and t, use: v = u + at. If you have s, u, and t, use: v = 2(s/t) − u . If you have s, a, and t, use: 13-Feb-2023
Detailed explanation-3: -v = u + at. v² = u² + 2as. s = ut + ½at²
Detailed explanation-4: -u = v – at. u2 = v2 – 2as. Where, Initial Velocity Solved Examples. Problem 1: Johny completes the bicycle ride with the final velocity of 10 ms-1 and acceleration 2 ms-2 within 3s. Answer: v (Final velocity) = u + at. ∴ (Initial velocity) u = 4ms-1 More items
