Question
l. A small cannon is situation atop Ve. At the moment shown, it fires a small ball straight up into the air with velocity w. The cart maintains a constant velocity. A coordinate system is shown in the figure to the right. cart which is moving with velocity Of the graphs shown bekow, which best represents the x- coordinate vs time graph of the ball? Justify your answer. 12 b. Of those graphs in part a), which best represents they-coordinate vs. time graph of the bar? Justify your answer e Or those graphs in part a), which best repeesents the x-coordinate vs. time graph of dhe cart? Justify your answer Activity 3B-1 (part a) d. Of the graphs shown to the right, which best represents the x-velocity vs. time graph of the ball? Explain. Of the graphs shown to the right, which best represents the y-velocity vs, time graph of the ball Explain. e. v f. What does the x-acceleration vs.time graph look like for the ball? g. What does the y-acceleration vs. time graph look like for the ball?Explanation / Answer
the ball has the horizontal velocity as cart along x-direction so (B) graph gives correct representation for the ball along x.
in the Y direction the ball has affected with acceleration due to gravity so option E is correct
the cart also moving along x direction with vc then option B is right.
d)option A because it is travelling with constant velocity.
e) option C represent correct result because a=-9.8m/s^2
f) coincides with acceleration axis since ax=0
g)parallel to acceleration axis at a=-9.8m/s^2
