A rotating wheel obeys the equation theta(t)=
8.9t-14.0t^2+1.84t^4 where theta is in radians and t is in
seconds.
What is ω at t = 4.0 s? Use 'rad/s' for your units.
What is α at t = 4.0 s? Use 'rad/s^2' for your units.
What is the average angular velocity between t = 1.0 s and 2.0
s? Use 'rad/s' for your units.
What is the average angular acceleration between t = 1.0 s and
2.0 s? Use 'rad/s^2' for...

On a separate sheet of paper, sketch the parameterized curve
x=tcost,
y=tsint for 0≤t≤4π. Use your graph to
complete the following statement:
At t=6t=6, a particle moving along the curve in the
direction of increasing t is moving _________ and _____________
(b) By calculating the position at t=6 and
t=6.01, estimate the speed at t=6.
speed ≈___________
(c) Use derivatives to calculate the speed at
t=6 and compare your answer to part (b).
speed ≈___________
question 1 (explain each code)
If more information if needed please let me know
a)t=linspace(0,1,1000); % Time t
Meaning:
b) for i=1:1000
xt(i)=v*cos(theta*pi/180)*t(i);
yt(i)=h+(v*sin(theta*pi/180)*t(i))-0.5*g*t(i)^2;
end
Meaning:
c) k = find(yt<0,1) % find index at which distance
becomes
fprintf('Ball hits the ground at distance of %d
meters',xt(k))
Meaning:
d) x=0:0.1:max(xt);
y=0;
plot(x,y*ones(size(x)),'--k')
Meaning:
You throw a rock at time t=2 s at an angle of theta=-2 degrees
with a speed of v=24 m/s from a high cliff. Calculate the speed of
the ball at the time t=11 s. Use g=10 m/s/s.

A government introduces a policy to subsidize its civilians in
the consumption of
a non-discrete good, say ?. To avoid some people who may abuse
the subsidy,
however, the government provides a 70% subsidy on the total
expenditure on ?
only up to the consumption of 4 units per month; any extra
consumption beyond
4 units and up to 8 units will only be eligible for a 30%
subsidy; and no more
subsidy will be provided...
I posted this question looking for a new paper not an
answer that's already posted on chegg since if someone already
turned in that paper it will show as a copied paper... the question
is..
