The 10 kg block is subject to the action of a force that has the constant direction towards the spring, with a magnitude F= 250 (1 + x) N, where x is measured in meters. If the coefficient of kinetic friction between the block and the horizontal surface is 0.20, and ks= 50 N/m Use the springs por your calculations Determine: a) The work done by all the forces acting on the block during a movement from A to B. b) If the block starts from rest at point A, determine its velocity at point B using the equation of motion (Newton's 2nd Law). c) Verify the speed obtained in b) through the equation of work and Kinetic Energy. d) Explain the differences between the two methods used to find the velocity, from the point of view of the volume of calculations. Recomendations: 1. No force (except weight) is constant throughout travel 2. Acceleration is not constant at any point along the way. 3. When applying Newton's second law, it is advisable to do it in two sections. 4. Review the…
A constant force of ''F'' acts on a mass as shown. The mass starts its motion from rest at position 1, the unstretched length of the spring is 250 mm, and the spring modulus is k=1,5 k?/m. Neglecting the friction, determine the required force ''F'' to cause the 2−kg mass to have a speed of v2=1,5 m/s at position 2.
