For motion 2, draw vectors in region II of the enlargement that represent the initial and the final momentum of the ball. Draw these vectors using the same scale that you need for motion I (i.e., the relative lengths should represent the relative magnitudes). Use these vectors to construct the change in momentum vector

- The magnitude of the net force exerted in the positive x direction on a 9.2kg particle varies in time as shown in the Figure below. If initially the velocity of the particle is +6m/s along the x axis, determine the final velocity of the particle after the 5.0s interval. Please note that (+) and (−) signs are used to denote positive and negative directions along the x axis! Don't forget to use the correct sign in your answer. Express your answer in units of m/sm/s using one decimal place.arrow_forwardThree 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). How far (in meters) will the block move in 5.0 s? Recall that it starts from rest.arrow_forwardShow your solution. Two cars, 100 apart, are about to collide. The cars, X & Y, are running at constant speed of 60kph &80 kph, respectively. a.) Illustrate the velocity vectors of the cars and formulate the equations. b.) What is the speed (in kph) of car Y observed on car X? c.) How many seconds will they collide?arrow_forward
- Given the following information, how would you find the magnitude of the acceleration of the system. Express youranswer in terms of known quantities such as m1, m2, theta, k, xs, x0, and g. "A ball of mass m1 and block of mass m2 are attached by a lightweight cord that passes over a frictionless pulley of negligible mass, as shown in the figure below. The block lies on a smooth plane inclined at an angle 'theta'. The ball is attached to a spring whose spring constant is k and equilibrium position x0. The spring is then stretched so it measures a length xs. You may use the fact that the force due to a spring is opposite the stretch and equal to −kΔxstretch. The system is then released. You can assume that the acceleration due to gravity is given as g, and use the consistent coordinate system specified for each object."arrow_forwardConsider the figure on the left, in which two blocks are being pushed across a frictionless surface. The blocks have masses m1 = 3kg and m2 = 15kg.(a) How hard are you pushing on m1, if the acceleration of m2 is 6m/s2? (You are pushing horizontally, as shown in the figure.) (b) What is the contact force between m1 and m2? (Still focusing on the figure on the left.) (c) Now consider the figure on the right, in which m2 is lifted off the ground. If the coefficient of static friction between m1 and m2 is 0.2 how hard would you have to push the blocks to ensure m2 would not slide down m1?arrow_forwardI need help with part c, can you write out the sentence with the answer please, thank you.arrow_forward
- Imagine a collision between two objects of identical mass, but with one of them at rest, as shown in the image. So m1 = m2 and v1 > 0, v2 = 0. Which object will experience the largest force? Explain your logic.arrow_forwardInstructions: With the simulation in picture 1 complete the table in picture 2. To do this: Measure the velocity orientation of each mass before and after the collision using an angle protractor. Give the angle to the positive x-axis. (1 (before), 2 (before), 1 (after), 2(after)) 2. Calculate your speeds before and after the collision according to the components x and y. (u1x, u2x, u1y, u2y, v1x, v2x, v1y, v2y) 3. Find the speed of each mass before and after the collision. ( u1; u2; v1; v2) 4. Calculate the amount of motion of each mass before and after the collision as well as the total amount of motion of your mass system always according to x and y. (p1x (before), p1x (after), p2x (before), p2x (before), p1y (before), p1y (before), p2y (before), p2y (after), Px (before), Px (after), Py (before), Py (after)) 5. Calculate the kinetic energy of each mass and the total kinetic energy before and after the collision.

If the block is stationary on a frictionless surface when hit, how fast does it move after the bullet emerges? please show your work, including diagrams, algebraic equations, and enough written explanations that somebody who is not familiar with the problem could understand what you are doing.arrow_forward
- Assume that the board you used was covered with two materials, material 1 and material 2. If the height where the wooden block started to slide down is higher on material 2 than on material 1, what can we say about the μs and μk associated with material 2 as compared to material 1? a. μs and μk on material 2 is higher than on material 1b. μs and μk on material 1 is higher than on material 2c. μs on material 2 is higher than on material 1, but μk material 1 is higher than on material 2d. μs on material 1 is higher than on material 2, but μk material 2 is higher than on material 1e. Regarless of any height, μs and μk is same on material 1 and material 2arrow_forwardFor the given several questions, consider the dot diagram below for the motion of an object along a horizontal surface.
