Unformatted text preview: ter? Friction force can be obtained by the product of the mass of the skaer with the retardation (negative acceleration). Given initial velocity of the skater is Given mass of the skater is Final velocity of the skater is Therefore the force exerted by the friction can be calculated Time taken by the skater to stop is using Newton’s second law of motion. Let a be the acceleration produced. From the equation of motion: Negative signs indicate the direction of the frictional force is opposite the motion of the...
