Question: A small rocket with initial mass 4 0 0 k g ( M o ) , is to be launched vertically. Upon ignition, the rocket

A small rocket with initial mass 400kg(Mo), is to be launched vertically. Upon ignition, the rocket consumes
fuel at the rate of 5kgs(me) and ejects gas at atmospheric pressure with a speed of 3500ms(Ve) relative to
the rocket. Determine the initial acceleration of the rocket and the rocket speed after 10 s , if air resistance is
neglected. Hint: consider the application of conservation of momentum.
