Question

could you please help with questions 3 and 16

3. [1pt] Answer True, False, or Cannot tell to each of the five statements below. E.g., if the answer to the first statement is 'true' and to the rest, `cannot tell', enter TCCCC. a. A 2 kg and a 3 kg ball are dropped from a tower. The net forces on each are the same. b. A box with a 100 kg passenger is catapulted straight into the air. The passenger's true weight is zero once the box is airborne. c. You are standing on a jet-powered platform that can move straight up or down. Your apparent weight is greater than your true weight if the platform is ascending and slowing down. d. The mass of an object depends on its location. e. An astronaut stands on a bathroom scale on the surface of Jupiter; the scale does not read the astronaut's true weight. Answer: Submit All Answers Last Answer: FCFFF to 16. [1 pt] On her flight home at Thanksgiving, Margaret decides to apply the physics she has learned in PHYC measure the speed of the aircraft when it takes off. She dangles her watch from a string while the aircraft accelerates down the runway. Draw a free body diagram of the watch. Using her protractor, she notices that the string makes an angle of 20° with respect to the vertical edge of the window as the aircraft accelerates on the runway, which takes about 25 s. Estimate the takeoff speed of the aircraft. Answer: [ Submit All Answers

note: question 3) I tried FCFFT FCFFC FCFFF and are all incorrect

Answer 1

3) F,T,T,F,T

-forces are different but time to reach the surface will be same

-normal force is zero so ya true

-yes during ascending and slowing down accleration increases , so wt. increases.

-mass is fixed quantity

-cannot say may , because wt chnages with accleration due to gravity
