in a rocket launching, the height h meter, the rocket reaches after t sec for the moment it was launched is given by h=xt-yt
the rocket altitude after 2 sec is 40 metres, and after 3 sec is 45 metres.
a. find x and y
b. altitude rocket after 5 sec

  • physics -

    40 = 2 x - 2 y
    45 = 3 x - 3 y

    120 = 6 x - 6 y
    090 = 6 x - 6 y

    inconsistent, no solution
