Anna Shcherbakova is a 2022 Beijing Olympics figure skating gold medalist for ladies’ singles. After warming up she starts her practice by skating towards the middle of the ice rink, 14 meters from the entrance. However, this time, one of her friends decided to trick her by pushing her towards the middle at a velocity of 1.2 m/s (disregard friction between the ice and her skates). Recovering from the shock 2 seconds after, she starts pushing herself forward at an acceleration of 0.5 m/s2. What velocity will she have when she reaches the middle of the rink?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
