An x-y coordinate system (in meters) is constructed on the surface of a pool table, and three objects are placed on the table as follows: a m1 = 1.1-kg object at the origin of the coordinate system, a m2 = 2.5-kg object at (x = 1.2, y = 2.0), and a m3 = 3.6-kg object at (x = 4.0, y = -1.2). Find the magnitude of the net gravitational force exerted by the other two objects on the object at the origin. Select an answer and submit.

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 56.0 kg. You pick up an object and drop it from rest, starting at a height of 2.35 meters above the floor, and it hits the floor 0.346 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body?     549.4 N     1,100 N     1,466 N     2,199 N

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 72.3 kg. You pick up an object and drop it from rest, starting at a height of 1.52 meters above the floor, and it hits the floor 0.223 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body? 1 2,210 N 2 2,947 N 3 4,420 N 4 709.3 N

An unfortunate astronaut loses his grip during a spacewalk and finds himself floating away from the space station, carrying only a rope and a bag of tools. First he tries to throw a rope to his fellow astronaut, but the rope is too short. In a last ditch effort, the astronaut throws his bag of tools in the direction of his motion, away from the space station. The astronaut has a mass of ma = 124 kg and the bag of tools has a mass of m = 13.0 kg. If the astronaut is moving away from the space station at Vj = 1.20 m/s initially, what is the minimum final speed vpf of the bag of tools with respect to the space station that will keep the astronaut from drifting away forever? Ub.f = m/s

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 71.1 kg. You pick up an object and drop it from rest, starting at a height of 1.82 meters above the floor, and it hits the floor 0.305 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body?     1,391 N     1,855 N     2,782 N     697.5 N

A person is crossing a bridge. The bridge is 3.2 meters long and is 25 kg. One side of the bridge rests on the ground while the other side of the bridge is elevated 25 degrees above the ground. The end of the bridge that is elevated is connected to a rope, which is attached to a overhanging section of a cliff. The person walking across is 62 kg, and walks three quarters of the way to the rope end of the bridge then stops. Please determine the magnitude of the force that the ground exerts on the bridge.

At the center of a 47.0 m diameter circular ice rink, a 56.0 kg skater traveling north at 2.60 m/s collides with and holds onto a 59.0 kg skater who had been heading west at 1.05 m/s. How long (in seconds) will it take them to reach the edge of the rink assuming negligible friction and drag?

You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. Your own body mass is 54.7 kg. You pick up an object and drop it from rest, starting at a height of 1.20 meters above the floor, and it hits the floor 0.396 seconds later. You can ignore air resistance. Based on the outcome of this experiment, when you step on the scale provided for you, what weight will it register for your body?
