Launch Failure.? A 7500-kg rocket blasts off vertically from the launch pad with a constant upward acceleration of 2.25 m/s2 and feels no appreciable air resistance. When it has reached a height of 525 m, its engines suddenly fail; the only force acting on it is now gravity. (a) What is the maximum height this rocket will reach above the launch pad? (b) How much time will elapse after engine failure before the rocket comes crashing down to the launch pad, and how fast will it be moving just before it crashes? (c) Sketch ay-t, vy-t, and y-t graphs of the rocket’s motion from the instant of blast-off to the instant just before it strikes the launch pad.
Adult 1/Med Surg Week 3 Hypertension Page 709 Hypertension AKA high blood pressure. Known as the silent killer. There are no symptoms that portray Hypertension. Hypertension affects the arteries. **The heart has to pump against systemic vascular resistance (SVR) to get the blood throughout the body. **We want the SVR to be low. If SVR is high, the heart has to pump harder against the resistance, which will cause HTN. Blood Pressure Good B/P-- <120/<80 Systole= heart contracts Diastole= heart relaxes BP is up= SVR is up BP is down= SVR is down Prehypertension= 120/80 **High BP is typically found when a patient comes into a clinic for another reason & the healthcare provider catches it. **We need 3 consecutive high blood pressures
