A bus is moving at a speed of 20 m/s, when it begins to slow at a constant rate of 5 m/s^2 in order to stop at a bus stop. if it comes to rest at the bus stop , how far away was the bus from the stop

Answer 1

Initial speed v_o = 20 m/s, a = -5 m/s² (slowing down), and final v = 0. Appropriate equation is v² = v_o² + 2aΔx, 0 = 400 - 10 Δx, Δx = 40 m.
