Question

( f(t)=n t^{2}-n t+1 )
( f(t)=50 t^{2}-50 t+1 )
( f(t) quad t=5=50 x_{2} S-50 times 5+1 )
( 21250-250+1 )
( =150001001 mathrm{km} mathrm{s} )

# A comet is heading for Jupiter with acceleration a lug = gof when f(x)=xg(x) = VX is given by f(t) = at - at +1. Then the velocity at time! (a) 900 kms ith acceleration a = 50 kms'. The velocity of th in the velocity at time t= 5 seconds is ............. (b) 1001 kms (C) 2001 kms The differ 150 met

Solution
