1) Based on your answer above, create a calculated column(USED THE TABLE PROVIDED BELOW) in your data table so that you create a linear relationship. Use the linear regression tool to find the equation for your relationship. Write your equation in the space below, (HINT)  your equation should show velocity(v), as a function of release height(h), . So it should be of the form v(h) 2) Are your results consistent with the Work-Kinetic Energy Theory? Explain. (HINT) Recall the Work-Kinetic Energy Theory: W=K

A weight lifter lifts a 380-N set of weights from ground level to a position over his head, a vertical distance of 2.40 m. How much work does the weight lifter do, assuming he moves the weights at constant speed? My answer was 855 This was my feedback Please fix this Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error. J

OBJECTIVE: Determine how physical work is related to the time to walk and hurry up a flight of stairs Determine how weight is related to physical work Determine how power is related to physical work Determine how time is related to power.   INSTRUCTIONS: Measure the vertical distance from the ground floor to the landing and from the landing to the 1st floor as shown below (convert to feet). Record this value on the data sheet, column B.  Note:  Your stairs might not have a landing – that’s ok.  Just measure the vertical height from the bottom to the top of the stairs.   Record your weight (pounds) in column A of the data sheet. Multiply column A and column B.  Record this value in column C. Measure the time it takes to walk (at a normal pace) up the stairs from the ground floor to the first floor – use the hand rail for support.  Measure 3 times and calculate the average time.  Record these values in column D. Measure the time it takes to briskly walk (not run) up the stairs…

Assume that it takes a net work of W to give an object a speed v and kinetic energy KE, starting from rest. What would be the object's kinetic energy (in terms ofKE) if a net work of 4.8xW to the object (again starting from rest)? We are asking how many KE's the new kinetic energy would be. If the new kinetic energy is nX KE, just enter n using one decimal place! Add your answer
