Three forces of magnitudes F1=4.0N, F2=6.0N, and F3=8.0N are applied to a block of mass m=2.0kg, initially at rest, at angles shown on the diagram. (Figure 1)In this problem, you will determine the resultant (net) force by combining the three individual force vectors. All angles should be measured counterclockwise from the positive x axis (i.e., all angles are positive). A.) What is the magnitude of the block's acceleration vector, a⃗ ? B.) What is the direction of a⃗ ? In other words, what angle does this vector make with respect to the positive x axis? C.) How far (in meters) will the block move in 5.0 s? Recall that it starts from rest.
The diagram shows overhead views of four situations in which forces act on a block that slides on a frictionless ice surface. In which situations would it be possible for the block to move along the floor with a constant velocity? (Assume the magnitudes of the forces can be adjusted slightly). I do not understand this at all. I know gravitational force is downwards, and frictional force is opposing the pushing force, but how do I solve this?
I created a free body diagram but need help explaining how the slope of the ramp can be used to determine the coefficient of friction. Im trying to use math to exaplain using μ = tan(θ) and my rise is 15cm and my run is 55cm. My teacher taught us SOH CAH TOA but im not sure how I would expalin using math. Please help me out!
The diagram shows the forces acting on a lorry as it travels along a flat road. a. Two of the forces have effects that cancel eachother out. Which two? Explain your answer. b. What is the resultant force of the lorry? Give it's magnitude and direction c. What effect will this resultant force have on the speed at which the lorry is travelling?
Handwritten Only. Two children pull a third child backwards on a snow-saucer sled exerting forces f1=10.5 N and f2= 8.5 N. Note that the direction of the friction force, F= 5.4 N, is unspecified; it will be opposite in direction to the sum of the other two forces. A) Find the magnitude, in meters per squared second, of the acceleration of the 44kg sled and child system. B) Let east be towards the right of the sketch, and let north be towards the top of the sketch. Assuming the sled starts at rest, find the direction of the velocity in degrees north of east.
The contestant now pulls the block of ice with a rope over his shoulder at the same angle above the horizontal as shown below. Calculate the minimum force Fhe must exert to get the block moving. (b) What is its acceleration once it starts to move, if that force is maintained?
If two tugboats pull on a disabled vessel, as shown here in an overhead view, the disabled vessel will be pulled along the direction indicated by the result of the exerted forces. (a) Draw a free-body diagram for the vessel. Assume no friction or drag forces affect the vessel. (b) Did you include all forces in the overhead view in your free-body diagram? Why or why not?
What is forces and motion? Do they have relationship with each other? How is their relationship? Finally, what is the importance of it. After answering the question how can you conclude this data given? (For Conclusion Part)
Two students need to change the position of a 150 kg piece of equipment inside a laboratory. The distance they need to drag the equipment is 10m. Knowing that the coefficient of kinetic friction between the equipment and the floor is 0.3. The figure below shows a top view, where the arrows represent the friction forces and the forces applied by the students. Given that θ=20° , that the forces A1(vector) and A2(vector) have the same magnitude and are symmetrical to the horizontal, and that the equipment was dragged at constant speed, calculate the work done by the friction force and the students in moving the equipment.
Hey! I’m confused on how to do this problem, the worksheet is dealing with Newton’s Second Law of Motion. Can someone please help me? Thanks
At a construction site, a pallet of bricks is to be suspended by attaching a rope to it and connecting the other end to a couple of heavy crates on the roof of a building, as shown in (Figure 1). The rope pulls horizontally on the lower crate, and the coefficient of static friction between the lower crate and the roof is 0.509. What is the weight of the heaviest pallet of bricks that can be supported this way? (Hint: Start by drawing appropriate free-body diagrams.) (Express your answer in pounds.) What is the friction force on the upper crate under the conditions given in Part 1? (Express your answer in pounds.)
