Arocket test sled accelerates at a constant rate of 25 m/s2 from rest while moving along a straight track. the rocket engine turns off instantly when the sled reaches a speed 37 m/s. the sled then moves freely (acceleration = 0) for a period of 7 s, after which the brakes are automatically applied giving a constant deceleration of -15 m/s2. what is the total distance that the sled moves?

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.
