Answer:
1000.66m
Explanation:
L1=1000m
Temperature 1=-20
L2=?
Temperature 2=40
Temperature difference=40-(-20)
40+20=60
inserting into the formula
l2=l1(1+α×changeintemperature)
L2=1000(1+11×10^-6 ×60)
L2=1000(1+6.6×10^-4)
L2=1000(1.000.66)
L2=1000.66m
469.24m. An airplane flying 60m/s at a height of 300m dropped a sack of flour that stack the ground 469.24m from the point of release.
This is a example of horizontal parabolic projectile motion,and we represents this motion in the coordinate axis, which means that the velocity has components in x axis and y axis.
The equation of components on the x axis.
, where x is the distance and Vox the initial velocity before the drop
The equation of components on the y axis.
, where y is the height, and the velocity in y component before the drop is 0, reducing the equation to
Clear t from both the equation of components on the x axis and the y axis:
and
Equating both equations and clearing the distance x:
Substituting the values:
