- A mover pushes a large packing crate across the floor in a straight line at a constant speed. What is the type of friction acting on the crate? kinetic ✓ Correct. 1-Because the crate is in motion, the type of friction exhibited in this case is kinetic friction. If the mover is applying a horizontal force of 110 N, what is the magnitude (in N) of the friction force on the crate? ⨯ Think about Newton's second law. If the velocity is constant, what's the acceleration? What's the net force? From this, if the mover pushes with a force in one direction, what must be the magnitude of the kinetic friction force in the other direction? N A large safe sits on a concrete floor. You push the safe horizontally, but the crate does not move. What type of friction force acts on the safe? static ✓ Correct. 2-Because the safe is motionless, the type of friction exhibited in this case is static friction. If the horizontal force you apply to the stationary safe above is 130 N, what is the…1. Look at the data: as the net force increased, what happened to the acceleration? Did it increase, decrease or stay constant? Why? 2. Did a change in the net force produce a change in acceleration by the same factor? Do the results agree with Newton’s 2nd Law?? ExplainThe 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?
- **please answer the last two parts only.** (f1s & acceleration of block 1) Block 1 (20 kg) is pulled by a rope from left to right up a ramp which is inclined 20 degrees from the horizontal. The rope pulls on block 1 with a force of 340 N parallel to the surface of the inclined plane. The coefficient of kinetic friction between the block and the surface equals 0.4.IN THE SPACE PROVIDED BELOW , draw the free body diagram for block 1 using the two-subscript notation from class. Assume that the x-axis is parallel to the incline and positive in the direction up the incline. After completing the free body diagram, enter below each force and its x & y-components. FORCES on BLOCK 1 Weight force on block 1 by EarthW1E = i + j NTension force on block 1 by RopeT1R = i + j NNormal force on block 1 by SurfaceN1S = i + j NFrictional force on block 1 by Surfacef1S = i + j N What is the acceleration a of block 1? a = i + j m/s21. Write Newton’s 2nd law along the ? and ? directions for both blocks considering their state of motion (accelerations). 2. What are the magnitude and direction of the frictional force on the upper box? 3. What is the magnitude of the applied force?Q1: Is the force of static friction constant as the incline rises? Explain your answer. Q2: If Mr. Einstein now wears ankle weights while sliding down, would the kinetic frictional force he experiences be the same, less, or greater than he experienced before? Would he accelerate faster? Would the coefficient of kinetic friction change? Please do not copy the answer from other source
- Two masses B and C are connected with a string passing over a friction less pully, assuming the coefficient of friction between the table and block is μ=0.4 , and the acceleration of gravity g=9.81 m/s2. Solve the following questions (show all the steps of your calculations): A. Draw the free body diagram of the two masses.B. Find an expression of the acceleration of the two masses in terms of ?? and ??.C. Determine the tension in the rope in terms of ?? and ??.D. If ??= ʎ kg, ?? = (ʎ-5) kg, determine the acceleration of two blocks and the tension in the rope.(ʎ= the final two numbers of your ID +10, and, gravitational acceleration, g = 9.81 m/s2).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?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?
- Draw the free-body diagram of the block. Using this diagram and your knowledge about Newton’s laws of motion, explain why is it that with 0.5 coefficient of friction, the minimum force required to move a 0.8kg-block is 3.8 N?1. Describe what you saw in the context of Newtons third law (equal and opposite forces): For every action, there is an equal and opposite reaction. Be careful here - where does the force of thrust come from? a. Which direction does the force of thrust point? Draw a free-body-diagram. Check that this makes sense given your answer to above.1 Is it possible for a body to move in a constant speed but a variable velocity? 2 When a body has a constant acceleration, does the direction of its velocity change or not? If yes, give one of your examples. 3 If an object is acted on under several forces, does the object have to have acceleration? 4 Does the direction of the net force acted on a body and the direction of motion of the body have to be the same?
