- Homework Statement
- Consider a ship mass of 2000000kg with propeller blades of radius 7m and it can push backwards to a speed of 2m/s. Given that density of water is 1000kg/m^3 , find acc of ship.

- Relevant Equations
- F=ma

upthrust = pgv

Hello.

Not sure how to even begin with this question honestly. Didn't learn anything about thrust regarding this topic so it got me dumbfounded.

Here's how I try to interpret it:

I'm assuming that the thrust created by propellers = net force of the ship, where I can use F=ma to find acceleration. The problem is I don't really know and understand how to calculate thrust using the density of water and velocity/radius of propeller. Any help will be grateful here. Thanks
