VRAAG 3 VRAAG 3 'n Bаl, A, wоrd vertikааl оpwaarts vanaf 'n hоogte, h, met 'n spoed van 15 m.s-1 gegooi. OP DIESELFDE OOMBLIK word 'n tweede, identiese bal, B, vanaf dieselfde hoogte as bal A laat val soos in die diagram hieronder aangetoon. Beide balle ondergaan vryval en tref uiteindelik die grond.  NEEM OPWAARTS AS POSITIEF. 3.1 Beskryf die term vryval. (2) 3.2 Bereken die tyd wat dit bal A neem om na sy beginpunt terug te keer. (4) 3.3 Bereken die afstand tussen bal A en bal B wanneer bal A op sy maksimum hoogte is. (7) 3.4 Skets 'n snelheid-tydgrafiek  vir die beweging van bal A vanaf die tyd wat dit geprojekteer is totdat dit die grond tref. Toon die volgende duidelik op jou grafiek aan: • Die beginsnelheid • Die tyd wat dit neem om sy maksimum hoogte te bereik • Die tyd wat dit neem om na sy beginpunt terug te keer (4)   [17]
