When the human body is at rest, the heart pumps 4.6 L of blood into the aorta every minute. During some exceptional exertion, such as playing sports, the amount of blood delivered to the aorta increases to 25 L every minute. If the area of the opening of the aorta is A = 0.81 cm2 What is the average velocity of blood as it enters the aorta in each of these cases?

A high diver leaves the end of a 5.5 mm high diving board and strikes the water 1.2 ss later, 3.5 mm beyond the end of the board.

We want to find the coefficient of restitution e between the ball and the floor. We will be able to measure the time of flight between subsequent bounces, but not the velocities before and after each impact. Question 1 a. Using the kinematics equation for position, find a relationship between the time of flight tn and the velocity of the ball after the nth bounce. You should obtain a quadratic equation that has two solutions for the time tm, but only one of them represents the time of flight. b. Using the kinematics equation for velocity and the relationship determined in the previous step, find the relationship between the velocity right after the nth bounce and the velocity right before the (n +1)th bounce? c. Given your answers to the previous parts of this question and the definition of €, find the coefficient of restitution e in terms of the subsequent times of flight tn and tr+1.

Problem 1: While sitting in physics class one day, you begin to ponder the workings of the analog clock on the classroom wall. You notice as the hands sweep in a continuous motion that there are exactly t = 35 minutes left in class. 11 10 Randomized Variables 3 t = 35 minutes Part (a) Through what angle (in radians) will the second hand turn before the end of class? Numeric : A numeric value is expected and not an expression. Oseconds . Part (b) Through what angle (in radians) will the minute hand sweep before the end of class? Numeric : A numeric value is expected and not an expression. Ominute =. Part (c) Through what angle (in radians) will the hour hand sweep before the end of class? Numeric : Anumeric value is expected and not an expression. Ohour = Part (d) Calculate the angular velocity of the second hand in radians per second. Numeric : A numeric value is expected and not an expression. Wseconds = Part (e) Calculate the angular velocity of the minute hand in radians per second.…
