Question

an 80 kg water skier is being pulled by a boat with a force of 220 n causing the skier to accelerate at 1.8m/s2. Find the drag force of the skeir

Answer 1

The drag force of the water skier is 144 N.

Step-by-step explanation:

To find the drag force of the water skier, we can use Newton's second law of motion which states that force equals mass multiplied by acceleration (F = ma).

In this case, the force exerted by the boat is 220 N and the acceleration of the skier is 1.8 m/s^2. The mass of the skier is 80 kg.

Using the formula, drag force (F) = mass (m) × acceleration (a), we can substitute the given values:

Drag force = 80 kg × 1.8 m/s^2 = 144 N

Hence, the drag force of the skier is 144 N.
