Answer 3

Calculation of Frictional Force on Ice

To calculate the frictional force acting on the skater, we can use the formula:

Frictional force = coefficient of friction × normal force

Where: - Coefficient of friction (μ) for ice is given as 0.015 - Normal force (N) is equal to the weight of the skater, which can be calculated as the product of mass and acceleration due to gravity (9.81 m/s²)

Calculation Steps

1. Calculate the weight of the skater: - Weight (N) = mass (kg) × acceleration due to gravity (m/s²) - Weight = 50 kg × 9.81 m/s²

2. Calculate the frictional force: - Frictional force = coefficient of friction × normal force

Let's calculate the frictional force.
