vel. at which time. tell me the way of throwing. is it horizontally or vertically or parabolic.

anonymous · Answer

initial velocities, and parabolic.

anonymous · Answer

here the horizontal distance(R) it travel is 
=initial horizontal vel.(Ux) * total time taken(T)
R =Ux*T
Ux=R/T=9.14/1.37 =6.67 m/s
now the total vertical displacement is zero as it start from the ground & end with it.
 vertical displacement(H) =Uy*T-1/2(a*T^2)      
 (Uy=initial vertical vel. ,a=vert. acc. = g=9.8)
H=Uy*T -1/2( g*T^2)
0 =Uy*1.37 -0.5*9.8*1.37*1.37
Uy =9.19/1.37= 6.713 m/s

so Ux=6.67 m/s
     Uy= 6.713 m/s
