1))) According to Newton’s laws, an object will remain stationary or move at constant velocity unless acted by a force. If a force (F) is applied, the object will accelerate according to F=m·a, where “m” is the mass of the object and “a” is its acceleration. The unit of force is the Newton (N), N is kg·m/sec a) Consider a stationary object with a mass of 5 Kg, acted on by a force of 10 N. What is its acceleration?...

1. Newton’s Laws and damped simple harmonic motion A particle of mass m = 5 moves in a straight line on a horizontal surface. It is subject to the following forces: an attractive force in the direction of the fixed origin O with magnitude 40 times the instantaneous distance from O a damping force due to friction which is 20 times the instantaneous speed the force due to gravity the normal force. The particle starts from rest at a distance...
