Two masses rest on a frictionless surface. You are given a spring scale and are asked to measure the acceleration of the masses for a given range of applied horizontal forces. You obtain an acceleration-vs.-force graph for each object. Unfortunately, the units on the spring scale are missing! However, you happen to know that the mass of object 2 is 0.250 kg. Knowing this, what is the mass of object 1? Round your answer to the nearest thousandths place. 16 7 14 12 2 1 10 acceleration (m/s^2) 2 4 5 6 7 8 9 10 force Your Answer: Answer units A Question 3 (1 point) Retake question Listen A 0.120 kg baseball travelling at 42.0 m/s strikes the catcher's mitt, which recoils backward 0.14 m as it brings the ball to rest. What was the magnitude of the average force applied by the ball on the mitt? Round your answer to the nearest ones place. Your
