Use Matlab to find the acceleration and jerk of the body with velocity

Use Matlab to find the acceleration and jerk of the body with velocity

v(t)=2000 ln[140000/(140000-2100t]-9.8t ,0<t<30

for time = 15 seconds, use forward method and start with step size = 3 seconds. make iterations of calculation until three significant digits.

This sounds like a homework assignment. Please post, what you have tried so far and ask a specific question about Matlab. The forum will not solve your homework.

Take the derivative of velocity to get acceleration.

Take the derivative of acceleration to get jerk.

Since you have an explicit expression for the velocity as a function of time, you can get explicit expressions for acceleration and jerk also. I have no idea why you are apparently instructed to use "forward iterations" since you can get the exact results analytically. Maybe you can post the entire text of the assignment so we can understand.
