Example 1: Let us consider the work example problem: A train covers a distance of 15 km and that the force is causing it to accelerate at a rate of 0.7 m/s 2. Determine the pulling force F. Answer: mgcosθμ k +mgsinθ Problem # 2 Two blocks of mass m and M are hanging off a single pulley, as shown. 1. Calculate the work done? Mass of the object is 1 kg. 1. Normal force – problems and solutions. Refer the below work physics problems with solutions and learn how to calculate force, work and distance. In physics, force problems typically ask you to predict what will happen when you apply force to an object, and usually there’s no handy illustration to help you visualize what’s being described. 1. The coefficient static friction is 0.4 and acceleration of gravity is 9.8 m/s 2. An object rests on a horizontal floor. Solved problems in Newton’s laws of motion – Force of the static and the kinetic friction. Three forces are involved in this situation: the force of gravity, pulling straight down; the normal force, or the force with which the ground is pushing against the vehicle, directed perpendicularly away from the ground; and the force of friction, directed in the opposite direction of the vehicle’s motion. Fortunately, you can create your own diagram so you can better picture what a question is asking you. Follow this seven-step method to solve force problems: Two objects m1 and m2 each with a mass of 6 kg and 9 kg separated by a distance of 5... Parabolic motion, work and kinetic energy, linear momentum, linear and angular motion – problems and solutions. Problems with Detailed Solutions Problem 1 (No friction) A 2 Kg box is put on the surface of an inclined plane at 27 ° with the horizontal. Problem # 1 A block of mass m is pulled, via pulley, at constant velocity along a surface inclined at angle θ. The surface of the inclined plane is assumed to be frictionless.
