Question

A particle falling vertically from a height hits a plane surface inclined to horizontal at an angle θ with speed v_o and rebounds elastically (Fig 4.7). Find the distance along the plane where if will hit second time.

(Hint: (i) After rebound, particle still has speed V_o to start.

(ii) Work out angle particle speed has with horizontal after it rebounds.

(iii) Rest is similar to if particle is projected up the incline.)

Answer 1

(Av_o²/g) sinθ
