simple graph sum

BITSAT 2015 Coaching › Mechanics questions › simple graph sum

what will be the shape of the graph when velcoity is plotted against distance

could anyone tell me how to solve these types of graph sums

forgot to add the motion is shm

@abhishek ya obviously...accel has to be uniform...if acceleration is non uniform them we cant predict wat will be the exact shape of the graph...

a = -kx
vdv/dx=-kx
âˆ«vdv=-kâˆ«x dx

v^2=w^2(A^2-x^2)}

were you having difficulties plotting this or arriving at this ?
