Two children fight over a toy. one pulls with a force of 8 n to the right. the other pulls with a force of 6 n to the left. what is the strength and direction of the net force on the toy?

Two particles of masses m and 2m are placed on a smooth horizontal table. a string, which joins these two masses, hangs over the edge supporting a pulley, which suspends a particle of mass 3m. the pulley has negligible mass. the two parts of the string on the table are parallel and perpendicular to the edge of the table. the hanging parts of the string are vertical. find the acceleration of the particle of mass 3m.

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
