A 750.0 N man, carrying a 2.0 kg physics textbook, stands at the center of a frozen pond of radius 10.0 m. He is unable to get to the other side since there is no friction at all between his shoes and the ice. To overcome his difficulty, he throws his textbook horizontally at a speed of 6.0 m/s toward the north shore. How long (in s) does it take him to reach the south shore

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

When the force acting on an object points at least partially in the direction of the motion the work done is considered to be negative
