(question 1) A person with a mass of 50 kilograms pushes a 2000-kilogram car to the right with a force of 500 Newtons. What is the force that the car applies to the person?
(question 2) An ice skater with a mass of 50 kilograms pushes another skater (with a mass of 40 kilograms) with a force of 25 newtons. How much acceleration does the 50-kg skater have?
(question 3) Two people are moving a heavy desk. One person pulls to the right with a force of 25 newtons, while the other pushes to the right with a force of 50 newtons. There is also 29 newtons of friction pointing to the left. what is the net force on the desk?
(question 4) Two people are trying to pull 5-kilogram block in opposite directions. The first person pulls to the right with a force of 25 newtons, and the second person pulls to the left with a force of 15 newtons. What is the acceleration of the block?
IK its a lot but I need help please

The astronauts on the space shuttle flights experienced an acceleration of 29 m/s2 (about 3 "g's") during lift-off. what upward force must the astronaut's seat apply to the astronaut in order to cause this acceleration? assume the astronaut's mass is 70 kg, and compute this force when the acceleration is near the earth's surface so their weight equals latex: mg m g .
