Ot ^ t, Ou = uu tv = u + tf. (Area= ut + hfV-) Fig. 8. 18. If a particle P moves horizontally fiom a point 0 withan initial velocity u, and its velocity is subject to a constantvertical acceleration g, its horizontal velocity subsequently re-mains u, whilst its vertical velocity in time t becomes… … Fig. 9. Fig. 10. Thus if P be the position of the particle at the end of tseconds, PN = ut, PM = i gt^ . Since ON also = hgi^ , the time of flight from 0 to P isthe same as the time of fall from 0 to S. Experiment to illustrate. Fig. 10 shews the component velocities (and also theresultant…
