An object with mass 80 kg moved in outer space. When it was at location <13, -19, -7> its speed was 5.0 m/s. A single constant force <180, 310, -190> N acted on the object while the object moved from location <13, -19, -7> m to location <19, -13, -12> m. Then a different single constant force <150, 260, 130> N acted on the object while the object moved from location <19, -13, -12> m to location <24, -18, -8>...
(b) An object with mass 80 kg moved in outer space. When it was at location < 7, -32, -2 > its speed was 18.5 m/s. A single constant force < 190, 410, -230 > N acted on the object while the object moved to location < 12, -36, -5 > m. What is the speed of the object at this final location? final speed = m/s
An object with mass 120 kg moved in outer space. When it was at location <15, -22, -3> its speed was 12.5 m/s. A single constant force <240, 400, -230> N acted on the object while the object moved to location <18, -29, -7> m. What is the speed of the object at this final location?
An object with mass 120 kg moved in outer space. When it was at location <7, -30, -7> its speed was 9.0 m/s. A single constant force <210, 400, -140> N acted on the object while the object moved to location <13, -34, -13> m. What is the speed of the object at this final location? Please explain how to solve. Thank you.
Problem 6.33 An Object with mass 90 kg moved in outer space, when it was at location <15,-31,-8> its speed was 6.0 m/s. A single constant force 180, 340. -140> N acted on the object while the object moved from location 15,-31,-82 m to location <18, -26, -14 m. Then a different single constant force <150, 240, 150 N acted on the object while the object moved from location <18, -26, -14 m to location <24, -35, -9 m. What...
An object which is originally at location 〈 -2,0,0 〉m moves to a location 〈 -5,0,0 〉m as shown in the diagram above. While it is moving it is acted on by a constant force of 〈 -23,0,0 〉N. How much work is done on the object by this force? W= As a result, the kinetic energy of the object: Stays the same. Increases. Decreases.
An object of mass 6.50 kg undergoes a displacement S= 11.5 m i + 5.5 m j while it is being acted on by a net force F = 5.9 N i -2.2 N j. a) How much work is done on the object by the net force? b) If the object above starts from rest, what is its speed after it has undergone the displacement described above?
An object of mass 2.5 kg has a momentum < 7, 7, 1 > kg m/s At this instant the object is acted on a by a force < 25, 50, 100 > N for 3 x 10-3s What is the momentum of the object at the end of this time interval? < 6.92, 6.85, 0.70 > kg m/s <0.07, 0.15, 0.30> kg m/s < 7.04, 7.08, 1.15 > kg m/s < 7.08, 7.15, 1.30 > kg m/s None of...
A 60.0 kg astronaut is in outer space far from any object that would exert a significant gravitational force on him. He is outside of his spaceship and, initially, is stationary with respect to it. He would like to move toward his spaceship, but his jet pack is not functioning. To start his journey to safety, he pushes a 2.00 kg mallet with a speed of 5.0 m/s in the direction away from the ship. What is the astronauts speed...
1. An object of mass 20 kg is released at point A, slides to the bottom of the 30° incline, then collides with a horizontal massless spring, compressing it a maximum distance of 0.90 m (see below). The spring constant is 425 N/m, the height of the incline is 2.0 m, and the horizontal surface is frictionless. (a)What is the speed of the object at the bottom of the incline? 4.15 m/s (b)What is the work of friction on the...
