A water skier has a mass of 80 kg and accelerates at 2 m/s². What is the net force acting on the skier?
To find the net force acting on the skier, we can use Newton's second law of motion, which states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration.
F = m * a
Where:
F = net force
m = mass of the skier (80 kg)
a = acceleration (2 m/s²)
Substitute the values into the formula:
F = 80 kg * 2 m/s²
F = 160 N
Therefore, the net force acting on the skier is 160 N.
