Question
Problem 10: While sunbathing on the balcony ofyour 3rd floor apartment, you notice someone drop a m 6.1 kg pumpkin from rest from the roof of the 5- story building across the street. Since you just completed a course on surveying, you know that the two identical buildings are d 29 m apart, and have floors that are h = 4.9 m tall. The first floor is at ground level, as shown Randomized Variable m 6.1 kg d=29m h=4.9 m ©theexpertta.com Part (a) Determine the magnitude of the angular momentum of the pumpkin, in kilogram meters squared per second, as observed by you immediately after it is dropped Numeric A numeric value is expected and not an expression. Part (b) Determine the magnitude of the angular momentum of the pumpkin, in kilogram meters squared per second, as observed by you as it passes the floor of the 4th floor balcony of the other building Numeric :A numcric valuc is expected and not an expression. Part (c) Determine the magnitude of the angular momentum of the pumpkin, in kilogram meters squared per second, as observed by you as it passes the floor of the 3rd floor balcony of the other building, directly across from you. Numeric A numeric value is expected and not an expression. Part (d) Determine the magnitude of the angular momentum of the pumpkin, in kilogram meters squared per second, as observed by you as it passes the floor of the 2ndnd floor balcony of the other building Numeric A numeric value is expected and not an expression Part (e) Determine the magnitude of the angular momentum of the pumpkin, in kilogram meters squared per second, as observed by you immediately before it hits the ground, at the bottom of the first floor Numeric A numeric value is expected and not an expression.Explanation / Answer
m=6.1 kg
d=29 m
h=4.9 m
use, angular momentum L=m*V*d
a)
here,initially speed v=0,
==> L=0
b)
at 4th floor,v=sqrt(2*g*2h)
and
L=m*V*d
L=m*sqrt(2*g*2h)*d
L=6.1*sqrt(2*9.8*2*4.9)*29
L=2451.71 kg.m^2/sec
c)
at 3rd floor,v=sqrt(2*g*3h)
and
L=m*V*d
L=m*sqrt(2*g*3h)*d
L=6.1*sqrt(2*9.8*3*4.9)*29
L=3002.72 kg.m^2/sec
d)
at 2nd floor,v=sqrt(2*g*4h)
and
L=m*V*d
L=m*sqrt(2*g*4h)*d
L=6.1*sqrt(2*9.8*4*4.9)*29
L=3467.24 kg.m^2/sec
e)
at 2nd floor,v=sqrt(2*g*5h)
and
L=m*V*d
L=m*sqrt(2*g*5h)*d
L=6.1*sqrt(2*9.8*5*4.9)*29
L=3876.49 kg.m^2/sec
