The horizontal and vertical components of the initial velocity
of a football are 20m/s and 30 m/s respectively. Assume that after
rising some height, the football returns back to the ground
level.
1) what is the speed of the football at 3s after launch?
2) to what maximum height does the football rise?
3)What horizontal distance does the football travel during its
flight?
Please show full explaination and steps for answer.
Let u(t) and w(t) be the horizontal and vertical components,
respectively, of the velocity of a batted baseball:
??=−?? and ??=−?−?? ?? ??
where ? is the coefficient of air resistance and g is the
acceleration of gravity.
Determine u(t) and w(t) assuming the following initial
conditions: ?(0) = ? cos ? and ?(0) = ? sin ?,where V is the
initial speed of the ball, and A is its initial angle of
elevation.
Let x(t) and y(t) be the...
Prepare a paragraph to tell us what is horizontal and vertical
analysis. State why vertical and horizontal analysis can be of
value to any company. How it might apply to your employer/business
or other business you know of?
Explain why
A) The pressure drops in a horizontally flowing fluid as the
velocity increases.
B) Heat’s effect on entropy is inversely proportional to the
temperature at which the heat enters or leaves.
C) One could never reach absolute zero.
1- If the velocity head is 250 mm then what is the velocity of
the fluid.
2-A tube, open at both ends, is placed into water at constant
temperature. How high does the water rise within the tube in mm?
The diameter of the tube is 10 mm. Assume the contact angle is
zero.
3- You measure air to have a velocity of 45 m/s in a pipe of
radius 2 cm. The pipe then expands until its cross-sectional area...
In regard to horizontal and vertical analysis do some research
and answer why these methods are used. What can be learned from
statements? How can the results be compared to other
corporations and why are ratios better than using dollars?
