While pecking on a tree, the woodpecker's head comes to a stop from an initial velocity of 0.600 m/s in a distance of only 2.00 mm. a) Extract and codify all the relevant information from the text. Make sure not to miss information stated implicitly! b) One of the units has a prefix. Using scientific notation, convert it into Sl unit without prefix. c) To find the acceleration, what is the most suitable kinematics equation from the information provided? d) Use the formula from part c) p calculate the acceleration. e) Calculate the stopping time. f) The tendons cradling the brain stretch, making its stopping distance 4.50 mm (great head and, hence, less deceleration of the brain). What is the brain's deceleration? DD

Learning Objectives: In this assignment students will use Newton’s laws and solvesystems of symbolic equations to find quantities of motion such as position, velocity,acceleration and time. Students will represent information in multiple ways. Studentswill make predictions and assess their work.Problem Statement: An object of mass m rests at the top of a smooth slope ofheight h, length L and angle ?. The coefficient of kinetic friction ??. A very smallpush overcomes static friction, and the object begins to slide down the slope.Using your knowledge of kinematics, determine a symbolic expression for the object’sspeed when it reaches the bottom of the hill. This should be in terms of some of all ofgiven/known variables m, h, L, g, ? and ??. Check the physical units of yourexpression.

A penguin starts from rest and accelerates across the snow at a constant rate until he hits the ice, as depicted in the figure below. He then throws himself down and begins to slide along on the frictionless ice. He then goes over the edge into an ice gully and slides up a vertical ice cliff on the other side. Speeds up to here then starts sliding Highest point. that he reaches Starts at rest D Snow Ice F a) Draw a curved line on your paper that represents the shape of the snow and ice (you don't have to draw the penguins). Add points to your drawing that are like the labeled points above. Along your line, draw an arrow to represent the penguin's veloc- ity at each of the labeled points, including roughly scaling the lengths of the velocity vectors to represent the penguin's speed at each point. If it is zero at any point then write "v = 0" by the point. b) Draw arrows to represent the direction of the penguin's acceleration at each of the labeled points. If the acceleration is zero at…
