A 100-kg object is moving at 20 m/s when a force brings the object to rest 3 points
in 1.5 seconds. If the same object moving at the same initial speed was
brought to rest in 3.0 seconds, then the required force would be
times the original value. Fill in the blank with the factor that would make
the statement correct. Then explain, in detail, how you picked your answer.​
