1.	A rocket with a lift-off mass 20,000 kg is blasted upwards with an initial acceleration of 5.0 ms^(2) . Calculate the initial thrust (force) of the blast.
Answer» Solution :Letrocketmovesin upwarddirectionwith accelerationaweigthandinitialthrustT onthe rocket `:. T= mg +ma` `=2 xx10^(4)(9.8+5)` `T =29 .6 xx10^(4) N` Whichis THRUST actingon rocket T = `3.0xx 15^(5) N`
