Question 4 1 pts A physics student records the data in the table below during a 1-D motion experiment with constant acceleration. Unfortunately he forgets to properly label the table before emailing it to his lab partners for analysis. As a result, they have to use their knowledge of kinematics to figure out how the table is organized and what the rows and columns represent. Use your knowledge of kinematics to select the correct answer below. Assume that all units...

Question 4 1 pts You pick up a textbook, with a mass of 0.5 kg. You lift the book off your desk a distance of 0.5 m, carry it 5 m horizontally, and then place it on the floor. The top of your desk is 1 m above the floor. The total change in gravitational potential energy of the book and Earth is 4.9 0 -4.9 2.45 0-245/ 7.35 22.05J -22.05

A person with mass mp = 74 kg stands on a spinning
platform disk with a radius of R = 2.37 m and mass md =
184 kg. The disk is initially spinning at ? = 1.9 rad/s. The person
then walks 2/3 of the way toward the center of the disk (ending
0.79 m from the center).
1) What is the total moment of inertia of the system about the
center of the disk when the person stands...

D Question 2 2 pts A donkey pulls a crate up a rough, inclined plane at constant speed. Which one of the following statements concerning this situation is true? The gravitational potential energy of the crate is increasing. O The donkey does "negative" work in pulling the crate up the incline. The work done on the crate by the normal force of the plane is not zero joules. The work done on the object by gravity is zero joules. Two...

PHYS 110 Lab #6 Wrap up question 1: Say the car in Collision B (1000 kg, 100 mph) takes 0.2 seconds to come to a stop rather than 0.1 s. Would you expect the damage to be the same as before, or would it be less? Justify your answer with a force comparison. Wrap up question 2: Using your energy numbers from your measurements, explain why the impact of the 100 mph car is more than twice as bad in...
