A positin-time graph for aparticle moving alo x axis is shown

1-find the average velocity in the time interval t=1.50 s to t=4.00
2-Determine the instantaneous velocity at t=2.00 s by measuring the slope of the tangent line shown in the graph
3-at what value of t is the velocity zero
*************
The position of aprticle moving along the xaxis in varies time according to the expression
x=3x^2
where is x is in metters and t is in seconds
Evaluate its position
1- at t=3s
2-at t=3s+(t2-t1)
3- evaluate the limit if x2-x1/t2-t1
t2/t1 approaches zero to find the velocity
*******************
Find the instantaneous velocity of the particle described in the graph

at the following times
1-t=1s
2-t=3s
3-t=4.5s
4-t=7.5
