An object moves in a straight line
9/zeqgobz 4 fm+yf j;1 2easqo o40gf9q+bw g4 on a level road. The variation of the object's distance

1. During the interval of $t=0.5\,s$ and $t=1.0\,s$, the object
2. Calculate the instantaneous speed of the object at $t=0.5\,s$ the answer is $v$ =
$m/s$
3. Determine the direction of the change in momentum of the object during the motion.
4. On the axes below, sketch a possible graph of the variation of velocity
v of the object with time
t. There is no need to add values to the axes.
