# Long question (20 marks)22. A point like object with mass m = 1 kg starts from rest at point x0 = 10 mand moves without any friction under a force F which depends on thecoordinate x as illustrated in figure below. The motion is confined to onedimension along x. a2. Sketch its kinetic energy as a function of x. [4]a3. Sketch its velocity as well as its acceleration as a function of time t. [6]Now consider a case when, in addition, a friction force of a magnitude of 1 Nis present for x ≥ 0.b1. Sketch how the velocity depends on x in that case. [6]b2. How many meters this point like object travelled during the time whenits position coordinate x was ≥ 0? [2]

Hi,

We know the force as a function of x using this graph under different x ranges.
Use this equation, calculate different parameters, ex- Kinetic energy = Work done = F * x
