Question 15 5 pts The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by 1 = (1.61 x 10'î +3.00 x 10°j)m and 7 = (1soi +213) The plane is most likely O just touching down. in level flight in the air. ascending O descending. O taking off.
5 pts The site from which an airplane takes off is the origin. The x axis points east; the y axis points straight up. The position and velocity vectors of the plane at a later time are given by i = (1.61 x 10°î +3.00 x 10°j) m and 7 = +(150i – 21ſ) The plane is most likely O just touching down. in level flight in the air. O ascending. O descending. O taking off.
An object with mass m is initially at rest at the origin z-0. At time t-0 it starts to accelerate with a changing acceleration along the +z direction. At time t = T it is at the point z=:T and its speed is measured as e(T) = vr 6. Find the for tr and τ in terms of F. m, and T
A particle inoves along the x-axis. It's position as a function of time is given by z (t)t+22- The following questions refer to that situation. Only consider times t greater than or equal to zero fno negative values of t. Note application of the derivative is finding the maximo and minima of functions. O 1m 0 2m D Question 7 1 pts For times t between t- 0 and t 3 s, what is the minimum value of x attained...

Question 21 10 pts An airplane takes off from rest. It accelerates 4 m/s2 for 35 seconds. What is its velocity at the end of the acceleration? How far did it go in the 35 seconds? Question 22 10 pts A boat sails 100 km east then 200 km 60° south of east. How far and which way is it from the origin?
A rhinoceros is at the origin of coordinates at time t 1 =0 . For the time interval from t 1 to t 2 = 14.5 s , the rhino's average velocity has x-component -3.2 m/s and y-component 5.7 m/s . a>At time t 2 = 14.5 s what is the x-coordinate of the rhino? b>At time t 2 = 14.5 s what is the y-coordinate of the rhino? c>How far is the rhino from the origin?
A particle poves along the x-axis. It's position as a function of time is given by z (t) =-31+ 2e-翅 The following questions refer to that situation. Only consider times t greater than or equal to zero (no negative values of t). Note Some of the questions ask about the maximum velocity attained, or the maximum x coordinate, etc. Hint: use calculus! A very important application of the derivative is finding the maxima and minima of functions 1 pts D...
A particle moves along a curve with parametric equations x(t) = ln(t+1), y(t) = sin(t), z(t) = 3t, where t is time. Determine the speed of the particle at t = 0.
An object with mAss Im is i along the +z direction. At time t = T it is at the pointz-2T and its speed is measured as v(T) nitially at rest at the origin -0. At time t-0 it starts to accelerate with a changing acceleration 4. What is the (a) 부 average power supplied by the force during the time interval T7 (b) (c) 부 (d) O (e)爭
