Explanation:
Detailed explanation-1: -The equation is s = ut + 1/2at^2, where s-distance, u-inititial velocity, and a-acceleration. Thanks!
Detailed explanation-2: -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
