Hi. *Problem solved.

A trolley of mass 930 g is held on a horizontal surface by means of two springs,one spring on the left and right respectively.The variation with time t of the speed v of the trolley for the first 0.60s of its motion is shown in the fig(It's a v-t graph,max y=8.0cms^-1 ,min x=0.0s & 0.6s) below.

Use the fig above to determine the distance moved during the first 0.60s of its motion.

The answer=0.031m +-.001m.I find using a triangle to find half of the distance,then multiply 2 to get the whole distance not satisfying.I used s=ut +at^2/2 also and still didn't get it.Any 1 pls tell of a way to get the ans?

Im sorry, but I dont understand what your talking about. Its not 'area', it represents something.

It's distance,which is represented under the area under the curve,how to find?

If you know calculus then you can calculate the exact area in many cases by finding an antiderivative.

There's no equation given for the graph,how?

Can you segment the area under the graph into nice geometric regions? By that I mean triangles and rectangles?

I've just added the graph pic on the first post,edited.If u 1 ,refer to that 1.
