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:
Considering north as positive Y axis
First 10 miles north means a positive 10 displacement along y direction
Second 20 miles south means a negative 20 displacement along y direction
Third 5 miles south means a positive 5 displacement along y direction
So total displacement = 10 - 20 + 5 = -5 miles displacement
So position vector of the final position = - 5 j
Answer:
Direction of force towards the center and string apply the force.
Explanation:
Lets take
Mass of yo-yo =m
Length of string = L
Angular speed = ω
The radial acceleration a = ω² L
Then the radial force on the yo yo given as
F = m ω² L
Then this radial force act towards the center of the circle formed by yo- yo.The force exerted by string.
So the direction of force towards the center and string apply the force.
Answer:
Vector Quantities Increase/Decrease in Temperature - The measurement of the medium's temperature is a scalar quantity; the measurement of the increase or decrease in the medium's temperature is a vector quantity. Velocity - The measurement of the rate at which an object changes position is a vector quantity.
