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
