Question

A graph between the square of the speed of a particle moving along a straight line and the distance s moved is shown in the figure. The acceleration of the particle in km h - 2 is –, 2250, 225, - 2250, - 225

MARKS App · Accepted Answer

∵ v 2 = u 2 + 2 a s ⇒ for v 2 - s graph slope = 2a from graph v 2 = - 2700 0.6 s + 3600 ∵ Slope = 2700 0.6 = 2 a ⇒ a = - 27000 12 = - 225 0
