Question

A particle of mass m=1.1 kg can move along the horizontal x axis subject to a single force that is conservative and whose potential energy is shown in the figure below. There is no friction in the problem

 

The positions marked in the Figure are x1=9.3 m, x2=13.02 m and x3=17.67 m, and the respective potential energy values ​​are U(x1)=6.6 J, U(x2)=1.2 J and U(x3)=4.8 J

At the beginning, the particle is at x=0 with speed vi= 2.2 m/s in the positive direction of the x axis. At this point, its potential energy is U(0)=9.6 J.

When the particle passes through position x2, what is its kinetic energy? Give your answer to two significant figures
