View Policies Show Attempt History Current Attempt in Progress A gymnast does a dismount and lands on a mat. During the time interval she is in contact with the mat and is slowing down, the average net force on her is \( \langle 0,2000,0\rangle \mathrm{N} \). The gravitational force by Earth on the gymnast has a magnitude of 590 N . The mat maximally compresses 1.8 cm during the impact. (Assume her body is stiff during the landing, which is not the best technique.) Part 1 Your answer is incorrect. What is the time interval of the impact? (i.e. the time interval between when she first touches the mat and when she comes to rest.) \( \Delta t= \) i ! s Hint Assistance Used You will need the mass of the gymnast. Apply the Momentum Principle to the gymnast during the collision with the mat. Note that her final \( y \)-velocity is zero. Assume a constant net force, then the average velocity is the one-half the sum of the initial and final velocity of the gymnast. Save for Later Last saved 1 second ago.

Mr. Smith, diagnosed with pneumonia, was in the hospital for several days and required multiple blood collections throughout the day. He was also receiving antibiotics by IV. After many venipunctures, it was very difficult to find a good vein that was not covered by hematomas. A PICC line was placed for blood collection and medication infusion. The doctor ordered an activated partial thromboplastin time (APTT), complete blood count (CBC), and basic metabolic panel (BMP) every 4 hours.1. What must the nurse do before collecting the specimen?

In plant height, the tall allele (T) is dominant to the short allele (t). From a cross between two heterozygous plants [Tall (Tt) x tall (Tt) = 3/4 tall (T_) and 1/4 short (tt)], you generate 282 tall progeny.

2. Consider the initial value problem y'(x) = 2y - y^2 - 1, y(0) = 4 (a) Find any and all equilibrium solutions. (b) Sketch a phase line for this differential equation, and use it to classify each equilibrium as asymptotically stable, unstable, or semi-stable. (c) Based on these conclusions, determine the asymptotic behavior of the above initial value problem. That is, starting from the initial value y(0) = 4, what value will y(x) approach as x \to \infty? (d) Apply Euler's method to numerically approximate the solution of the initial value prob- lem over the domain 0 \le x \le 3 using a step size of h = 0.5. (e) Does the behavior of your numerical solution agree with your earlier asymptotic analysis? If not, what went wrong with the numerical solution process, and how would you suggest fixing it?

2.4-5 Theorem (Equivalent norms). On a finite dimensional vector space X, any norm $|| \cdot ||$ is equivalent to any other norm $|| \cdot ||_0$. Proof. Let dim X = n and {$e_1, \dots, e_n$} any basis for X. Then every x ? X has a unique representation x = $a_1e_1 + \dots + a_ne_n$. By Lemma 2.4-1 there is a positive constant c such that $||x|| \ge c(|a_1| + \dots + |a_n|)$. On the other hand the triangle inequality gives $||x||_0 \le \sum_{j=1}^{n} |a_j| ||e_j||_0 \le k \sum_{j=1}^{n} |a_j|$, $k = \text{max} ||e_j||_0$. Together, $a||x||_0 \le ||x||$ where a = c/k > 0. The other inequality in (3) is now obtained by an interchange of the roles of $|| \cdot ||$ and $|| \cdot ||_0$ in the preceding argument.
