It is s(t)=245+24.5t-4.9t(sqrd) meters from the ground (t) after it is thrown. s(t) = displacement function that describes the position of the ball from the ground at time t.(adsbygoogle = window.adsbygoogle || []).push({});

Determine height of building, time it takes the ball to reach the ground and the velocity when it hits the ground.

I've been messing around with first, second derivatives and breaking down the original equation into t=10 and t=-5 but I don't know where to go from here.

Help apperciated.

i should mention i took physics 2 years ago and dont remember much of it
