Near the surface of the earth, the speed \( (v) \) of an object falling freely from rest and the distance \( (s) \) it falls during time \( t \), where \( g \) is 9.8 meters \( / \mathrm{s}^{2} \), can be found as follows. \[ v(t)=g t \text { and } s(t)=\frac{1}{2} g t^{2} \] 13 When an object falls freely near the earth, what is the distance traveled by the object during the time interval 1 second to 2 seconds?

You have a summer job at your university's zoology department, where you'll be working with an animal behavior expert. She's assigned you to study videos of different animals leaping into the air. Your task is to campare their power outputs as they jump. You'll have the mass \( m \) of each animal from data collected in the field. From the videos, you'll be able to measure both the verti- cal distance \( d \) over which the animal accelerates when it pushes off the ground and the maximum height \( h \) it reaches. Your task is to find an algebraic expression for power in terms of these parameters. 9.- Una persona empuja un escritorio de 60 kg y lo acelera a razón de 1.4 m/s \( { }^{2} \), ¿cuál es el peso de ese escritorio y la fuerza que aplica la persona sobre él? Question 4. The distance, \( d \) metres, which an object falls, varies directly as the square of the time, \( t \) seconds, for which it has been falling. If an object falls 78.56 m in 4 s , find (to two decimal places): a. the constant of variation - Workspace + Check answer Question 4. The distance, \( d \) metres, which an object falls, varies directly as the square of the time, \( t \) seconds, for which it has been falling. If an object falls 78.56 m in 4 s , find (to two decimal places): a. the constant of variation - Workspace Una mujer de 70 kg de masa se balanea sobre uno de sus tacones, si el tacón es circular con superficie de \( 2 \mathrm{~cm}^{2} \) ¿Que presión ejerce sobre el suelo?. Question 4. The distance, \( d \) metres, which an object falls, varies directly as the square of the time, \( t \) seconds, for which it has been falling. If an object falls 78.56 m in 4 s , find (to two decimal places): a. the constant of variation - Workspace + Check answer b. the formula connecting \( d \) and \( t \) 6. Identificacion de magniludes indica si la siguiente situación es un caso de magnitud directa o inversa y explica por qué" - Un auta viaja a velocidad constonte. Cuanto mator sea el tiempo que se martenga esa vebcidad, mator será la distancia recorida. La altura de un acantilado es de 80 m , si lanza horizontalmente un prouectil con velocidad de \( 10 \mathrm{ml} / \mathrm{s} \).
