On which of the following objects does the Earth exert the largest force due to gravity? Assume the objects are all located on the surface of the earth. (A) A pen with a mass of 0.1 kg (B) A person with a mass of 100 kg (C) A car with a mass of 1500 kg (D) The Earth exerts the same gravitational force on all of these objects
Correct is given, please explain why for each Concept Question 4 – An object is initially at rest. A net force (which always points in the same direction) is applied to the object so that the power supplied by the net force is constant. As the object gains speed, a) the magnitude of the net force decreases. b) the magnitude of the net force increases. c) the magnitude of the net force remains constant. d) the magnitude of the net...
A coordinate system (in meters) is constructed on the surface of a pool table, and three objects are placed on the table as follows: a 10.0 kg object at the origin of the coordinate system, a 17.0 kg object at (0, 2.0), and a 27.0 kg object at (4.0, 0). Find the resultant gravitational force exerted by the other two objects on the object at the origin. magnitude direction
Rank the following objects according to the amount of momentum they have, from least to greatest. Specifically indicate any ties. Object A: mass 2.5 kg, velocity 1.0 m/s east Object B: mass 3.0 kg, velocity 0.90 m/s west Object C: mass 3.0 kg, velocity 1.2 m/s west Object D: mass 4.0 kg, velocity 0.50 m/s north Object E: mass 4.0 kg, velocity 0.90 m/s east
for both questions Two objects with masses represented by m, and m2 are moving such that their combined total momentum has a magnitude of 17.7 kg. m/s and points in a direction 71.5° above the positive x-axis. Object my is moving in the x direction with a speed of V1 = 2.90 m/s and my is moving in the y direction with a speed of v2 = 3.07 m/s. Determine the mass of each object in kilograms. kg m2 -...
An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 4.2× 104 kg, and the force causes its speed to change from 7100 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.3× 106 m determine the magnitude of the force.
An asteroid is moving along a straight line. A force acts along the displacement of the asteroid and slows it down. The asteroid has a mass of 5.4× 104 kg, and the force causes its speed to change from 6500 to 4500m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 2.4× 106 m determine the magnitude of the force.
