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 y
Vera_Pavlovna [14]
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

Fungi, however, decompose other matter, and have cell walls made of chitin. This would fit the description.
