A car traveling at 10 m/s slams into a trash can on the side of the road. The trash can sticks to the front of the car and they move as one object. If the momentum is

conserved, what would happen to the velocity of the car after the collision?

The velocity would decrease

It would remain the same

The velocity would increase

The car comes to rest

Consider a file currently consisting of 200 blocks. assume that the file control block (and the index block in the case of indexed allocation) is already in memory. calculate how many disk i/o operations are required for contiguous, linked, and indexed (single-level) allocation strategies, for each of the conditions listed below. in the contiguous-allocation case, assume that there is not room to grow at the beginning but there is room to grow at the end. also assume that the block information to be added is stored in memory.
