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? DDi got 1.392x10^-6 but my sender was incorrect , can you help me solve to find the answer in mV2. The position of a drone as a function of time is given by *(t) = ( 8 i + 1.5 k) + (-3 î + 2 j) t – 0.5 t2 j The units are missing in the constant coefficients above, i.e., "0.5" should be "0.5 m/s2". Include the correct units on all the constant coefficients in your answers below. a. What is the x-position of the drone as a function of time? b. What is the y-position of the drone as a function of time? c. How far away is the drone from its starting position at t = 3s? d. What is the acceleration vector? е. What is the velocity vector as a function of time? (One way to do this is to take the time derivative of the position vector.) f. Make a sketch of the x, y, and z positions of the drone as function of time. You just need the general shape. time time time
- can you show me how to do part d as well?I believe that part C is wrong and isn't the answer that my instructor has provided me with. Is there any other method to solve this problem?a)Find an expression for the bullet's initial speed v_B in terms of m, M, k, and d. Express your answer in terms of the variables m M k d b)What was the speed of a 1.8 g bullet if the block's mass is 1.1 kg and if the spring, with k = 37 N/m , was compressed by 16 cm? Express your answer in meters per second. c)What percentage of the bullet's energy is "lost"? Express your answer in percent to four significant figures.
- Please help me with these problems. We are using algebra based physics, not calc based6. A clock is showing the time as exactly 3:00 p.m. and 25 s. If the tip of the second hand is directly below the tip of the hour hand, and if the length of the second hand is 9 cm, what is the length of the hour hand? Note: While the second hand moves the minute and hours hands also move!1.
