Thank you for the opportunity to help you with your question!

4) if the track has 10 degree down grade

f=ma

20+5*9.8 sin 10=5*a

a=28.5/5

a=5.7 m/s^2


5)10 degree up grade

20-5*9.8*sin 10=5* a

5a=20-8.5

a=11.5/5

a=2.3 m/s^2

Please let me know if you need any clarification. I'm always happy to answer your questions.
