F=ma F/m=a 400N/50kg=a Therefore, a = 8m/s^2 Example. Calculate the acceleration of a boat that has been cruising at 15 m/s but speeds up to 45 m/s in about 6 seconds. Don’t forget your units, m/s2. In order to calculate the acceleration of the boat we first have to identify the suited formula for acceleration in this scenario. Hence, a = vf – vi / t. Vi = 15 m/s Vf = 45 m/s T = 6 seconds Solution: A = 45 m/s – 15m/s / 6s A = 5m/s^2
