A 450.0 kg boat experiences two simultaneous forces. The motor exerts a force of 100.0 N to accelerate the boat forward, while an unknown drag force pushes in the opposite direction. The boat accelerates forward at 0.1330 m/s2. Calculate the drag force acting on the boat.

The drag force is![D = 40.15 \ N](/tpl/images/0802/2824/80d7c.png)
Explanation:
From the question we are told that
The mass is![m = 450.0 \ kg](/tpl/images/0802/2824/e75ea.png)
The acceleration![a = 0.133 m/s^2](/tpl/images/0802/2824/ba462.png)
The force due to the motor is![F_m = 100 \ N](/tpl/images/0802/2824/6c80e.png)
Generally the net force acting on the boat is mathematically represented as
=>![F = 450.0 * 0.1330](/tpl/images/0802/2824/3fd60.png)
=>![F = 59.85 \ N](/tpl/images/0802/2824/8625e.png)
Generally the drag force acting on the boat is mathematically represented as
=>![D = 100 - 59.85](/tpl/images/0802/2824/5543d.png)
=>![D = 40.15 \ N](/tpl/images/0802/2824/80d7c.png)
