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.
I've already worked out the vertical and horizontal components
so far for this question. Vertical component=16.34 and horizontal
component=25.16 but I got no idea what to do from here. A polo ball
is hit from the ground at an angle of 33 degrees upwards from the
horizontal. If it has a release velocity of 30 m/s and lands on the
ground.
Based on the initial release parameters, what will the polo
ball's vertical and horizontal velocity components be at the...
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...
Determine the x- and y-intercepts (if any), and vertical and
horizontal a symptotes of the rational function r, given by
r(x) =3x^2+ 18x+ 24 / x^2−3x+ 2
and then use this information to sketch a graph ofr. As part of
your analysis, you should explicitly examine the behaviour of the
function on both sides of each vertical asymptote, and evaluate the
function at appropriate test points.
determine the vertical and horizontal asympotes (enter your
answers as a comma- separated list of equations. If an answer does
not exist enter DNE)
F(x)=1/x^2+4x-21

Pressurized water (pin= 10 bar, Tin= 110°C) enters the bottom of
an L= 10-m-long vertical tube of diameter D= 88 mm at a mass flow
rate of m˙= 1 kg/s. The tube is located inside a combustion
chamber, resulting in heat transfer to the tube. Superheated steam
exits the top of the tube at Pout= 7 bar, Tout= 600°C. Determine
the change in the rate at which the following quantities enter and
exit the tube: (1) the combined thermal and...
