Question

5.11 A truck starts froin rest'and accelerates uniformly at 2.0-m s2. At t= 10 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 =
lls? (Neglect air resistance.)​

Answer 1

velocity 11 metre per second

acceleration 10 or 9.8metre per second square equal to gravity of earth

as velocity of ball and acceleration of ball are perpendicular to velocity and acceleration of truck so truck velocity and acceleration does not affect ball velocity and acceleration
