Find ax = d^2x/dt^2 and ay = d^2y/dt^2 at given time t. Find net acceleration and then the net force.

So i find the derrivative of the x and y then plug in t=2.10?

Yes. Find the derivative twice to get the acceleration.

After that i take the sum of the accelerations at 2.10 multiplied by the mass 3.40?

To find the net acceleration you have to find theAfter that i take the sum of the accelerations at 2.10 multiplied by the mass 3.40?

ax and ay are perpendicular to each other. You can't add then directly to get the resultant acceleration.
