Question

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.

Answer 1

Answer:

The  drag force is $D = 40.15 \ N$

Explanation:

From the question we are told that

  The mass is  $m = 450.0 \ kg$

  The acceleration $a = 0.133 m/s^2$

The force due to the motor is  $F_m = 100 \ N$

Generally the net force acting on the boat is mathematically represented as

    $F = m * a$

=>  $F = 450.0 * 0.1330$

=>  $F = 59.85 \ N$

Generally the drag force acting on the boat is mathematically represented as

     $D = F_m -F$

=>  $D = 100 - 59.85$

=>   $D = 40.15 \ N$
