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...
