Question

Deadline: 100% until Sunday, November 24 at 11:59 PM Problem 1 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 0.25 m from the one remaining 1.5-kg bowling pin. 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.) 1.1 nN Submit You currently have 5 submissions for this question. Only 10 submission are allowed. You can make 5 more submissions for this question.

Please help me! I've done it several times and it doesn't work out, and I only have 2 attempts. Pleaseeee, Thanks a lot.

Answer 1

Well, the bowling pin is neither spherical nor a point mass, but I guess we have to apply Newton anyway:
F = GmM / d²
F = 6.674e−11N·m²/kg² * 7.0kg * 1.5kg / (0.25m)² = 1.12e-8N
or 11.2 nN (nanoNewtons)

Efficacy? Kramer would be better off blowing on the bowling pin.

I hope it was helpful.. please rate me positive
