A ball is set in motion at P on a frictionless surface. It moves up slope PQ, along the horizontal surface QR and finally descends slope RS. [Figure showing a ball moving from P up a slope to Q, then horizontally along QR, then down a slope from R to S.] Which graph could represent the variation with time t of the ball's speed v as the ball moves from P to S?
Agraph where speed v decreases from P to Q, remains constant from Q to R, and increases from R to S.
Bgraph where speed v decreases from P to Q, then decreases further from Q to R, and increases from R to S.
Cgraph where speed v increases from P to Q, remains constant from Q to R, and decreases from R to S.
Dgraph where speed v decreases from P to Q, remains constant from Q to R, and decreases from R to S.
