1. The problem statement, all variables and given/known data A model rocket accelerates upward from the ground with a constant acceleration, reaching a height of 76 m in 7.2 s. What is the acceleration (in m/s 2)? What is the speed (in m/s) at a height of 76 m? 2. Relevant equations V=Vo+at X=Xo+Vot+1/2at^2 V^2=Vo^2+2at(X-Xo) 3. The attempt at a solution I tried 76=1/2a(7.2)--> 76=3.6a-->21.1=a but it was wrong. Please help me!
