Mass of box 30 kg.
Theta is 15 degree.
A constant force is applied to a 10 kg box, giving it an acceleration of 25 m/s2. What is the magnitude of the applied force? How much work has been done when the box moves 100 m?
(10 pts) A constant force is applied to a 10 kg box, giving it an acceleration of 25 m/s a. What is the magnitude of the applied force? 10. b. How much work has been done when the box moves 100 m?
A jet aircraft with mass of 631,405.4 kilograms is flying straight downward. At an instant the plane's engine is producing an downward thrust (force) of 3,329,281.8 Newtons and air resistance is exerting a force of 714,785.5 Newtons upward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "down" as positive.
A jet aircraft with mass of 582,731 kilograms is flying straight upward. At an instant the plane's engine is producing an upward thrust (force) of 2,224,800 Newtons and air resistance is exerting a force of 90,000 Newtons downward. What is the acceleration of the plane in m/s2 at that instant? Note: In this problem, we define "up" as positive.
What maximum acceleration can the truck have before the box slides backward? Answer in units of m/s2. 012 10.0 points Two blocks connected by a string are pulled across a rough horizontal surface by a force applied to one of the blocks, as shown. The acceleration of gravity is 9.8 m/s. 3 kg 6 kg u= 0.48 If each block has an acceleration of 3.3 m/s? to the right, what is the magnitude of the applied force?
Mary applies a force of 72 N to push a box with an acceleration of 0.58 m/s2. When she increases the pushing force to 84 N, the box's acceleration changes to 0.85 m/s2. There is a constant friction force present between the floor and the box.
3. A 20 Kg box, initially at rest, is pushed for 2 meters with a force of 50 Newtons. If the frictional force is 30 Newtons, what is the kinetic energy of the box at the end of the 2 meters? Note: this is not a machines problem A see-saw (or a lever) for a playground is 10 meters long. The fulcrum, or pivot point, is placed 2 meters from one end and 8 meters from the other end. What...
