I tried to do it but I'm unsure of my answers, can you go through and try to solve them? You only have to answer the paper on top but you need the graph found on the bottom of the 2nd paper that's labeled as question #2

Section 1: Free Response - questions 1-3 40 minutes recommended (c) Calculate how high the rocket will go. X = Xo + up t + 2 a + 2 0+ 0( 2) + + 120 ) (212 *= 40 15 10 B Velocity (m/s) IC A 5 Ide 26 25 SO 10 15 20 25 Time (s) 2. A block with mass of .4 kg is moving in one dimension with a net force acting on it. The velocity time graph for the block's motion is shown above. The object is at a position of 0 m at the beginning of its motion, and the positive direction is to the right. (a) Use the area below to make an acceleration time graph for the block. Label the scale on the axes. Acceleration (m/s?) 10 15 20 25 Time (s) (b) Calculate the final position of the object. X = x+v + +!.Section I: Free Response - questions 1-3 40 minutes recommended (c) During which labeled section of the graph is the net force zero? Check all that apply. XAXBXC Justify your answer. The block will always have gravity acting onit (d) Calculate the size of the net force for the first three seconds of the block's motion. (e) From 15 to 25 seconds, In which direction is the block moving? Justify. opposite to the direction it was moving during the first 5 seconds, This is because the graph shows negative velocity ii. Which way is the net force acting on the block? Justify. to the left, because it is being forced in a negative direction 3. A cart moves on a straight flat track. The mass of the cart is .5 kg. The velocity time graph of the cart is below
