I need to multiply each element of a vector of five values by another vector 2000 values.

MATLAB Courseware - Intro to Engineering course

I am trying to solve this problem of plotting the motion of a projectile against time at five given angles. But I keep getting errors. I understand the error, it is happening because there are only five values in theta but 2000 in t, so the multiplication is not working. But I don't know how to fix it.

I have tried to write it two different ways, one without a for loop and and with a for loop. None of them works. In the for loop I just get a graph with one plot, not five plots.

Please could you help me.
