Question
Chapter 7, Problem 74QAP
To determine
(a)
What is Sally's speed immediately after throwing the boot if Sally finds herself stranded on a frozen pond so slippery that she can't stand up or walk on it, to save herself, she throws one of her heavy boots horizontally, directly away from the closest shore, sally's mass is 60 kg, the boot's mass is 5 kg, and Sally throws the boot with speed equal to 30.0 m/s?
To determine
(b)
Where is the center of mass of the Sally-boot system, relative to where she threw the boot, after 10.0 s?
To determine
(c)
How long does it take Sally to reach the shore, a distance of 30.0 m away from where she threw the boot? For all parts, assume the ice is frictionless

- A man holds a double-sided spherical mirror so that he is looking directly into its convex surface, 33 cm from his face. The magnification of the image of his face is +0.17. What will be the image distance when he reverses the mirror (looking into its concave surface), maintaining the same distance between the mirror and his face? Be sure to include the algebraic sign (+ or -) with your answer.arrow_forwardHow do you draw a diagram of the ruler and mass system in equilibrium identifying the anti-clockwise torque and clockwise torque?
