1.  Oliver, whose mass is 65 kg, and Olivia, whose mass is  45 kg, sit 2.0 m apart in their physics classroom. a) What is  the force of gravitational attraction between Oliver and  Olivia? b) Why don’t Oliver and Olivia drift toward each  other? 2.  When Royce was 10 years old, he had a mass of 30 kg.  By the time he was 16 years old, his mass increased to 60  kg. How much larger is the gravitational force between  Royce and Earth at age 16 compared to age 10? 3. On February 20, 1962, John Glenn became the first  American to orbit Earth. If John Glenn weighed 640 N on  Earth’s surface, a) how much would he have weighed if his  Mercury spacecraft had (hypothetically) remained at twice  the distance from the center of Earth?  4. Mr. Gewanter, whose mass is 60.0 kg, is doing a physics  demonstration in the front of the classroom. a) How much
