using basic differentiation formulas I need help with question 3.
3. If a ball is given a push so that it has an initial velocity of \( 5 \mathrm{~m} / \mathrm{s} \) rolling down a certain inclined plane, then the distance it has rolled after \( t \) seconds is \( s(t)=5 t+3 t^{2} \) (a) Find the velocity after \( 2 \mathrm{~s} \). (b) How long does it take for the velocity to reach \( 35 \mathrm{~m} / \mathrm{s} \) ?
Expert Answer
Solution:- Distance rolled is given by s(t)
