A 2.3 kg box, starting from rest, is pushed up a ramp by a 10 N force parallel to the ramp. The ramp is 2.0 m long and tilted at 17 degrees. The speed of the box at the top of the ramp is 0.80 m/s. (Consider the system to be the box + ramp + earth.) A.) What is the equation for conservation of energy for the system? B.) How much work W does the force do on the...
Question 4 8 pts A box of mass m = 7 kg is being pushed up a ramp that is angled 15 degrees above horizontal. The pushing force P = 49 N. The coefficient of kinetic friction is 0.215. At a certain time the velocity of the box moving up the ramp is 1.0 m/s. How far will the box been pushed during the next 3.0 seconds assuming the same pushing force is applied? In your solution you must show:...
The 52 kg block starting at rest is pushed 7.8 m up a ramp at an angle θ = 27.0° to the horizontal in 17 s. If the coeficient of kinetic friction is 0.17: a) What is the acceleration of block? m/s/s b) What is the force used to push the block up the ramp? N
A 22.7-kg box is being pushed from the bottom to the top of a frictionless ramp. When the box is pushed at a constant velocity, the nonconservative pushing force does 58.0 J of work. How much work is done by the pushing force when the box starts from rest at the bottom and reaches the top of the same ramp with a speed of 1.50 m/s?
True or False: A boy pushed a box with a weight of 300N up a ramp. He said that, because the ramp was 1.0m high and 3.0m long, he must have been pushing with force of exactly 100N. If possible, can you please explain why. Thanks!
3. (20 points) A block m = 5.00 kg is pushed up an inclined plane of angle 60.0°, as shown in Figure 4. There is friction between the surface of the block and plane. The coefficient of static friction is his = 0.400, and the coefficient of kinetic friction is pk = 0.300. (a) Find the minimum applied force F such that the block remains on the plane without moving. (b) If F = 60.0 N and the length of...
A box with a mass of 10 kg is pushed with a constant force of 100 N a distance of 3.0 m up a ramp that makes an angle of 30 from the horizontal. The coefficient of kinetic friction between the box and the ramp is 0.35. a. Compute the work done by each of the four forces acting on the box. b. Assuming the box starts at rest, determine the speed of the box at it reaches a distance...
A 10.0-kg microwave oven is pushed 8.00 m up the sloping surface of a loading ramp inclined at an angle of 36.7 ∘ above the horizontal, by a constant force F⃗ with a magnitude 109 N and acting parallel to the ramp. The coefficient of kinetic friction between the oven and the ramp is 0.259. A-Assuming that the oven is initially at rest, use the acceleration to calculate the oven's speed after the oven has traveled distance 8.00 m ....
A 90.0 kg box is pushed by a horizontal force F at constant speed up a frictionless ramp which makes an angle of 43.0 deg with the horizontal. Find the magnitude of the applied force F.
A 25.0-kg box is released at the top of a frictionless ramp that is inclined at an angle of 35.0◦ with the horizontal. The box slides 1.50 m down the ramp before you catch it and bring it to a stop in 0.400 m. Assuming you pushed on the box with a constant force that was parallel to the ramp as you caught it, what was the magnitude of the force you exerted on the box to bring it to...
