1) A net force of 20 N is applied to the right on an object. If the acceleration of the object is 2.5 m/sec, a) What is the mass of the object? (8 kg) b) What is the weight of the object? (78.4 N) c) What would the acceleration be if the force was cut in half? (1.25 m/sec) 2) If a car has a mass of 2000kg and it is accelerating at 2.1 m/sec, a) What is the net force on the car? (4,200 N) b) If the engine provides a force of 5000 N forward, what must be the magnitude and direction of the other force acting on the car? (800 N backward) 3) A 2000 kg spaceship is being pushed by two astronauts. The first is pushing to the right with a force of 10N and the second in pushing to the left with a force of 20 N. Assuming we can ignore the force of gravity, a) Draw a Free Body Diagram showing this situation. b) What is the net force acting on the spaceship? (10 N Left) c) What is the acceleration of the spaceship? (0.005 m/sec Left) d) If both astronauts were pushing to the right, what would be the net force and the acceleration of the spaceship? (30 N right and 0.015 m/sec) 1) A net force of 20 N is applied to the right on an object. If the acceleration of the object is 2.5 m/sec, a) What is the mass of the object?
