a. I need to find the v(t) and a(t) of s(t)=4t^5/2 - 15t^2 +t -3 I need to know how to start...something with the displacement b.find t when the acceleration is 0

Velocity I got 10t^4-30t+1 Acceleration I got 40t^3-30 now do I have to plug the 0 in these answers or the original equation for part b. Thanks I appreciate your help!

its the first one
