Question: A lawn mower with a mass of 10 kg is being pushed by a force of 100 N downward at 45* below the horizon. If the coefficient of kinetic force is 0.35, find the force of friction acting on the lawn mower and the lawn mower's acceleration. The response must be typed, single spaced, must be in times new roman font (size 12) and must follow the APA format.
A uniform rod rotates in a horizontal plane about a vertical axisthrough one end. The rod is 6.00?m long,weighs 11.0?N, and rotatesat 210 rev/min clockwisewhen looked at from above.
Calculate the gravitational potential energy U of this system. Take the potential energy to be zero when the two objects are far apart. Use Fx=-dU/dx to find the magnitude and direction of the force on the particle.
