1.

A rocket is fired vertically up from the ground and it ascends with a resultant acceleration of 10 m//s^(2). The fuel of the rocket is finished 1 minute after firing. The velocity (v) versus height (h) graph for entire journey is: (g = 10 m//s^(2))

Answer»




SOLUTION :`BAR(AB) = (1)/(2) g t^(2)= 5 xx 60 xx 60m = 18KM`
`bar(BC) = ((600) (600))/(20) = 18km, bar(AC) = 36km`

`v^(2) = {{:(+0.02h, 0 le H le 18km),(-0.02(h-36), 18km le h le 36km),(+0.02 (36-h), 36km ge h ge 0km):}`
