An object moves in a straight line on a level road. The variation of the object
h7wf mz.y7f/d 6d- fyk's distance d with time t is shown on the graph belo
.6mwfdz-ffkh7 /y yd7w
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.
