A shopper pushes a 7.5 kg shopping cart up a 13 degree incline. Find horizontal force needed to give the cart an acceleration of 1.41 m/s^2.(adsbygoogle = window.adsbygoogle || []).push({});

I know the answer is 28N, but I haven't yet figured it out.

I did F=ma F=(7.5)(1.41)cos13= 10.30

what didn't I do?

thanks
