Please answer this questions :$1.$ the objects illatitum acceleration was at the time interval$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ its magnitude was$\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ its unit$\_\_\_\_\_\_\_\_\_2.$ The object experienced a decelerating at a certain time interval, which was between$\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$ second. $3.$ Where is the time interval in which the object acceleration was zero$\_\_\_\_\_\_\_\_\_\_\_\_$ second$\mathrm{.}4.$ The object initial velocity is$\_\_\_\_\_\_\_\_\_\_5.$ When the object was at rest?$\_\_\_\_\_\_\_\_\_\_\_\_\_\_6.$ What's the initial position? Can you find it from the graph?$7.$ Can you find its travelled distance in $80$ sec$.,40$ sec$.?8.$ Draw the $($position $-$ time$)$ graph$\mathrm{.}9.$ Draw the $($acceleration $-$ time$)$ graph.
