1. A plane curve has been parametrized with the following
vector-valued function, r(t) = (t + 2)i + (-2t2 + t + 1)j a.
Carefully make 2 sketches of the plane curve over the interval . (5
pts) b. Compute the velocity and acceleration vectors, v(t) and
a(t). (6 pts) c. On the 1st graph, sketch the position, velocity
and acceleration vectors at t=-1. (5 pts) d. Compute the unit
tangent and principal unit normal vectors, T and N at...
I only need parts E, F, I and J. Don't worry about the others.
Thanks.

A model airplane weighing 520 g is attached to a rope of length
1.9 m and allowed to fly at a constant height 1.3 m above the
ground where the rope is attached to a rock. The propeller puts out
a constant force 1.4 N. At time t = 0 s, the plane moves
counterclockwise (looking down at it) at a speed 2 m/s.

Consider permutations of the 26-character lowercase alphabet
Σ={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z}.
In how many of these permutations do
a,b,c occur consecutively and in that
order?
In how many of these permutations does a appear before
b and b appear before c?
