A 2.56 kg cart moving along a horizontal track in the positive x direction has a changing force exerted on it. The force exerted on the cart is plotted in the graph shown. Note that the friction between the cart and track is negligible. a.-Calculate the work done in joules on the cart when it has reached a displacement of 27.9 cm along the track. b.-If the cart is moving with a speed of 2.31 m/s when it has reached a displacement of 27.9 cm along the track, calculate how fast (in m/s) the cart was moving at the start (at displacement = 0).

Question
A 2.56 kg cart moving along a horizontal track in the positive x direction has a changing force exerted on it. The force exerted on the cart is plotted in the graph shown. Note that the friction between the cart and track is negligible.
a.-Calculate the work done in joules on the cart when it has reached a displacement of 27.9 cm along the track.
b.-If the cart is moving with a speed of 2.31 m/s when it has reached a displacement of 27.9 cm along the track, calculate how fast (in m/s) the cart was moving at the start (at displacement = 0).
