Question

The accompanying graph of position x versus time t represents the motion of a particle. If p and q are both positive constants, the expression that best describes the acceleration α of the particle is, a = − p − qt, a = − p + qt, a = p + qt, a = p − qt

MARKS App · Accepted Answer

From graph V first increases then decreases Hence a is earliar positive then negative a = P − qt
