Problem 69P

Reconsider Prob. 3–73. Using EES (or other) software, investigate the effect of water c.epth on the force exerted on the plate by the ridge. Let the water depth vary from 0 to 5 m in increments of 0.5 m. Tabulate and plot your results.

Physics 105 Week 2 Notes By Lauren Faris Chapter 2: 1­D Kinematics  Sig figs are important! They do not all follow the rules with addition/subtraction. It depends on the last digit that makes a big enough difference.  Vectors need 2 components: magnitude and direction.  Scalars indicate only magnitude.  You add 2 vectors by placing them head to tail.  With vectors, b + (-b) = 0 is additive inverse.  With vectors, R = a – b = a + (-b) (vector subtraction).  A y Asin(theta)  A x Acos(theta)  Relations among vectors do not depend on the origin or the orientation of the axes.  Multiplying a vector by a scalar changes the magnitude, not the direction: a * s = sa  The scalar product can be positive, negative, or zero.  A unit vector has a magnitude of 1 without units.  Any vector can be expressed as: A = A i + Axj + Ayk z  The vector product, or cross-product, of two vectors is: C = A x B  The direction of the vector product can be found using the right hand rule.  The vector product is not commutative: A x B = -B x A  The study of motion is called kinematics.  Forces cause motion.  A displacement vector starts at an object’s initial position.  The change in a particle’s coordinate (along the x-axis) is its 1-D displacement vector: deltaX = X – X a2d th1 average x- velocity is Vavg-x= deltaX / deltaT  Average speed is the ratio of the total distance traveled and the total time duration that is a scalar quantity.  S avg= total distance / deltaT  Instantaneous velocity is at
