Given s = 4t + 11t3, find the velocity when t = 1 s.

Question

velocity in m/s =

My Answer:
S'=4+33t^2
=4+33
=4+33
=37

velocity in m/s = 37

Can you please confirm this is correct.
Thank you

Answer 1

S = 4t + 11t^3.
S = 4*1 + 11*1^3 = 4 + 11 = 15 m/s.

NOTE: 1 cubed = 1*1*1 = 1.

Answer 2

oops! I didn't realize you were doing
calculus.

Your calculus is correct.
