Best ResponseYou've already chosen the best response.2now,v=u+at 0=4.51 + (9.81)t t=0.46seconds

Best ResponseYou've already chosen the best response.2Again, v^2=u^2+2as 0^2=(4.51)^2 + 2(9.81)s s=1.04 m

Best ResponseYou've already chosen the best response.2So, maximum height = 1.19+1.04 m = 2.23m

Best ResponseYou've already chosen the best response.2Now, s=ut+1/2 at^2 2.23 = 0*t + 1/2 (9.81) t^2 t=0.67 seconds

Best ResponseYou've already chosen the best response.2So, total time = 0.46+0.67 =1.13 seconds
