(a(i))[1]
Calculate the initial weight of the rocket.
(a(ii))[1]
Define, in words, the term weight.
(b(i))[2]
Describe the motion of the rocket: From O to A From A to B
(b(ii))[2]
Draw a tangent to the graph at time = $400\,\text{s}$, then use it to calculate the rocket’s acceleration at this time. Show your working.
(c)[2]
Explain in terms of forces why the rocket reaches terminal velocity as it travels through the atmosphere back to the Earth.
