1.2. FORCES AND MOTIONpage 132013Q2A rocket, initially at rest on the ground, accelerates vertically.It accelerates uniformly until it reaches a speed of 900 m/s after 30 s.After this period of uniform acceleration, the rocket engine cuts out. During the next 90s, theupward speed of the rocket decreases uniformly to zero.(a) On Fig. 4.1, plot a speed-time graph for the rocket for the first 120s of its flight.speedm/stime/sFig. 4.1(b) Using the graph,(i) calculate the acceleration during the first 30s,acceleration =(ii) determine the height reached by the rocket after 120s.height reached =KS VENTUR

For the first t=30 s, the flight accelerates uniformly to a velocity v=900m/s. For the next t=90/s…
