PLEASE HELP! A car moving with constant acceleration covers the distance between two points 100 metres apart in 11 seconds. Its
speed as it passes the second point is 13 m/s.
What is the speed (to 1 decimal place) at the first point?

Help plsss

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
