Physics

An object of mass 4.15 kg undergoes an acceleration of 3.5 m/s^2for a period of 7.0 seconds. It then undergoes an acceleration of-4.2 m/s^2 for a period of 18.0 seconds. If the initial velocity ofthe object is 4.01 m/s and it first experiences the accelerationwhen it is at the origin, plot by hand on graph paper (to scale)the force, velocity, and position graphs as functions of time.Explain why your graphs look the way they do and include allrelevant equations.

ForForce Time graph Force is directly proportional to the mass and accelerationand force F ma Since in our case mass is constant forentire time period and mass m 415 kg and so force will varryaccording to the value of accelerationa for period of first 7 second the acceleration is constant soforce will be also constantacceleration a 35 ms2so Force F 415 35 14525 Nb for period of next 18 second after changed value ofacceleration a 42 ms2it remains constant soforce will also    See Answer
