I need some help on this question for maths!!
I don't even know where to start 😥.

The speed V m/s of a rollercoaster at time t s is given by v(t) = 1/20 ( 50 root t + 20t^2 - t^3)
The distance s m travelled by the rollercoaster in the first 20s is given by s = Integral 20 at the top 0 at the bottom v(t) dt
Find the value of s

The question has told you what you need to do - integrate the velocity function with respect to t. It's even told you the limits to use. Is it the integration that is the problem?

(You'll get more answers to a question like this if you post in the maths forum.)

Ohh yes of course! I was just being stupid! Thank you
