v (m/s) 817.32- t (s) 19.46 102.775 A sounding rocket is launched from sea level. Its speed is shown as a function of time in the graph above. The rocket has an initial mass of 810.7 kg. The flight is built up of two phases: 1) The propelled phase during the first 19.46 s In this phase the rocket is propelled by the rocket engine. 2) The 'coasting' phase from 19.46 s onward In this phase the rocket engine has burned out. Assume that gravity does not change with altitude and that air resistance can be neglected. Questions: RK a) Determine the acceleration during the first phase.
