Homework Help: physics

Posted by Hope on Tuesday, December 1, 2009 at 6:36pm.

A 1.6 kg particle moving along the x-axis experiences the force shown in the figure. The particle's velocity is 4.2 m/s at x = 0 m.

The figure or graph has F (N) along the y axis and velocity along the x axis. A diagonal line drops from positive 10 force to -10 force from 0 cm to 4 cm. and crosses the x axis at 2 cm.

What is its velocity at 2 cm and 4 cm?
What formula do I need to use?
