The velocity of a flow is given by u = 6 + x0.4 m/s. what is the convective acceleration at x= 5.2 (in m/s2)?

Under the action of a constant force an object accelerates at 7.8 m/s2. what will the acceleration be if (a) the force is halved? (b) the object's mass is halved? (c) the force and the object's mass are both halved? (d) the force is halved and the object's mass is doubled?

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost
