4.11 A truck starts from rest and accelerates uniformly at 2.0 m s−22.0 \mathrm{~m} \mathrm{~s}^{-2}. At t=10 st=10 \mathrm{~s}, a stone is dropped by a person standing on the top of the truck ( 6 m high from the ground). What are the (a) velocity, and (b) acceleration of the stone at t=t= 11s? (Neglect air resistance.) (a) velocity (b) acceleration
