11) Bob is moving a 15 kg box along a horizontal floor, by pushing down on the box at an angle = 30° below the horizontal with a force of F = 80 N and there is a frictional force of 50 N acting on the box as he pushes. What is the horizontal acceleration of the box? box 12) Using the same information in the above problem, Bob is moving a 15 kg box along a horizontal floor, by...

Allison is pushing a box to the right on a horizontal floor. The magnitude of the force of friction between the box and the floor is 40N. Allison pulls up and to the right with a force of 150N at an angle of 35 degrees to the floor. The box slides to the right at 3m/s^2 without moving up or down. (The x axis is horizontal and positive toward tht right. The y axis is vertical and positive is upward)...

N1 weight Work and Kinetic Energy - 4 Forces - Horizontal Motion This problem is similar to lecture example and discussion problem. As shown in the figure, a 25.5 kg block is pulled to the right by force F = 79 N. The coefficient of kinetic friction between the block and the floor is uk = 0.26. The block moves through a distance of 18.00 m. DON"T use scientific notation. Review on application of Newton's second law. Step 1: Start...

Sample Class Problems-Force and Acceleration Prob#l: Two people are pushing a stalled car (the mass of the car is 1850kg). One person applies a force to the car, while the other applies a force of 395N. Both forces act in the same of 560N also acts on the car, but in a direction opposite force arises because of friction and the extent to which the pavement opposes Find the acceleration of the car. direction. A third force to that in...

ements Constants ents SOLUTION We will look at an example where several forces are acting on an object, but in this case the forces are not all along the same axis. As shown in (Figure 1), a car engine with weight to hangs from a chain that is linked at point to two other chains, one fastened to the ceiling and the other to the wall. Find the tension in each of the three chains, assuming that is given and...

Physics 120 Worksheet 9- Moment of Inertia and Statics Problem 4. Analyzing Torque- You take the wheel from Problem 3 and drill a tiny hole through the center of the x so you carn mount the wheel in an axle. Now you tie three different pieces of string to the wheel and apply the three tension forces of IN to the wheel. Fri is applied to the top of the wheel and points left. Frz is applied to the bottom...
