Which is the best answer to complete this sentence for our IPC - B class,... According to Newton’s first law of motion, a moving object that is NOT acted on by an unbalanced force will

• remain in motion.

• eventually come to a stop.

• change its momentum.

• accelerate.

According to Newton’s first law of motion, an object at rest that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• remain at rest

If Thomas uses a force of 26 N exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration? (F=ma)

• The one with a mass of .78 kg will have the greater acceleration.

• The one with a mass of .52 kg will have the greater acceleration.

• They will both accelerate at the same rate.

• Do not have enough information to answer that question.

Kenny and Kameron are involved in a two man tug-of-war contest. On one side Kenny pulls with all his might with 1000 N of force to the south, the other side Kameron is pulling in the opposite direction with all his might with 950 N of force to the north. What is the magnitude and direction of net force in Kenny and Kameron's personal Tug-of-War battle?

• 50 N to the North

• 1950 N to the South

• 1950 N to the North

• 50 N to the South
