Help please. Teacher hasn't returned my work on this yet, and we're having a quiz on Monday. A 2.75-kg cat moves in a straight line (x-axis). The graph on the right shows the x-component of the cat’s velocity as a function of time. What is the net force on the cat? a. 0b. 27 Nc. 11 Nd. 2 N The maximum net force occurs during the time interval a. t = 0 to t = 10 secondsb. t = 6 to t = 10 secondsc. t = 2 to t = 6 secondsd. t = 0 to t = 2 seconds The net force on the cat is equal to zero between the time intervala. t = 6 to t = 10 secondsb. t = 2 to t = 6 secondsc. t = 0 to t = 10 secondsd. t = 0 to t = 2 seconds Thanks!
A sled is tied to a tree on a frictionless, snow-covered hill, as shown in the second figure in the right. If the sled weighs 80 N, find the a) force exerted by the rope on the sled; and the b) normal force exerted by the hill on the sled.
Draw the complete free body diagram of a a 1000.0 kg block being pushed forward 10.0 N by a penguin, pushed backwards by Mr. Universe with 200.0 N, and an elephant pushing it forward with 410.0 N of force. Calculate the acceleration that this block experiences, and in what direction does it move. How much frictional force and in what direction must it be applied such that the block undergoes static equilibrium? plz show work so I can understand
Our goal in this activity is to explore the force that seems to pull an object down the ramp, that is, parallel to the ramp surface. But your force diagram does not have a force in this direction. Let's explore why. Notice that the force of gravity is neither parallel to, nor perpendicular to, the ramp surface. Try to add two more force vectors to your force diagram that break the force of gravity into components parallel to and perpendicular to the ramp surface.
Based on the image provided, which picture shows contact force? How about non-contact force? Differentiate contact from the non-contact force? What specific kind of force is present in picture 1? How about in picture 2? Please answer the questions above and encode your answers
Solve the problem and answer the questions that follow. Would the force required to get the mass to start moving up the ramp be higher or lower than the force you calculated in the problem above? ______________________________________________________________________________ • Would the force required to keep the mass moving up the ramp be higher or lower than the force required to get the mass to start moving up the ramp? Why?
From Figure 101, what is the free-body diagram at the point where the greatest number of forces are concentrated?
Consider a cart moving along a horizontal table at constantacceleration. On your own, sketch below the forces you believe are acting on the cart at threedifferent time s. Be sure to indicate the relative size of those forces by the relative sizes of yourdrawn vectors. (Assume no friction.)
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?
PLEASE WRITE THE ANSWER IN 10 MINUTES!!! A block of mass m=10kg is being pulled with a force F as shown in the figure below. F is increased gradually until the block starts to move. If the block starts moving when F=60N, what is the coefficient of static friction between the block and the surface? Express your answer using two decimal places and take g=9.80m/s2.
When you push a 1.80-kg book resting on a tabletop, it takes2.25 N to start the book sliding. Once it is sliding, however, ittakes only 1.50 N to keep the book moving with constant speed.What are the coefficients of static and kinetic friction betweenthe book and the tabletop? Show your work and explain.
Hi, the first three parts of this problem have been answered, I just need the answer for the part below that is in BOLD. Thanks! Assume the three blocks (m1= 1.0 kg, m2 = 2.0 kg,, and m3 = 3.5 kg) portrayed in the figure below move on a frictionless surface and a force F = 48 N acts as shown on the 3.5 kg block. Three blocks of mass m1, m2, and m3 are placed on a horizontal surface. Block m1 is taller than m2 and touches its leftmost surface. Block m3 is some distance to the right of block m2. A cord, passing over block m2, connects blocks m1 and m3. A horizontal force vector F is applied to block m3 and directed rightward. Determine the acceleration given this system (in m/s2to the right). a = (F) / (m1 + m2 + m3) = (48.0) / (1+2+3.5) = 7.3846 ≈ 7.39 m/s2 Determine the tension in the cord connecting the 5kg and the 1.0 kg blocks (in N). F-T = m3a (48) – T = (3.5)(7.39 m/s2) T = 48 – 25.865 = 22.135 ≈ 22.14 N Determine the force exerted by the 1.0 kg block on the 2.0 kg…
