Unit 19: Prelecture / Openstax Ch 11.1-11.3 / Checkpoint / Homework/ Homework: HW12: Angular Momentum & Static Equilibrium & Gravitation Deadline: 100% until Friday, November 22 at 11:59 PM Problem 1 Kramer goes bowling and decides to employ the force of gravity to pick up a spare." He rolls the 7.0 kg bowling ball very slowly so that it comes to rest a center-to-center distance of 0.10 m from the one remaining 1.5 kg bowling pin. 1) Determine the force of gravity between the ball and the pin and comment on the efficacy of the technique. Treat the ball and pin as point objects for this problem. (Express your answer to two significant figures.) nN Submit

Answer 1

1] Force of gravity = Gm1m2/r

= 6.67e-11*7*1.5/0.1^2

= 7.00e-8 = 70e-9 N

= 70 nN answer

This force is very small to topple the ball, so it may not be effective.
