Problem 34DQ

On the moon, ?g? = 1.62 m/s2. If a 2-kg brick drops on your foot from a height of 2 m, will this hurt more, or less, or the same if it happens on the moon instead of on the earth? Explain. If a 2-kg brick is thrown and hits you when it is moving horizontally at 6 m/s, will this hurt more, less, or the same if it happens on the moon instead of on the earth? Explain. (On the moon, assume that you are inside a pressurized structure, so you are not wearing a spacesuit.)

Step-by-Step Solution:

Solution to 34DQ Step 1 Acceleration due to gravity in moon g =1.62m/s 2 m Acceleration due to gravity in earth g =9.8m/s 2 e Mass of the brick =2kg W =2x1.62=3.24N m W ex9.8 = 19.6N Velocity of brick in moon, m/s P ,Momentum of brick in moon= mxv=2x2.61=5.22kgm/s…….1 m Velocity of the brick in earth, PeMomentum of the brick in earth =12.52kgm/s Since, PePmherefore the falling brick will hurt more in earth than in moon.
