(High school physics) 1a) How much work is done in lifting a 25kg Christmas gift to a height of 15m? 1b) How much work is needed after lifting the Christmas gift, to carry it horizontally 250 m?
How much power is done against gravity in lifting a 3Kg object through a vertical distance of 40cm in 10 seconds?
Which required more work: lifting uniformly a 50.0 kg crate a vertical distance of 2.0 meters or lifting a 25.0 kg crate a vertical distance of 4.5 meters with a 1.0 m/s^2 acceleration?
A physics student does 100J of work lifting a 20kg box off the floor. How high does he lift the box?
(a) How much work must be done to raise a 2.00 kg mass a vertical distance of 1.00 m by pushing it up a frictionless inclined plane oriented at an angle of 300 with respect to the horizontal? (b) What is the magnitude of the force needed to do this work? (c) What is the distance through which the force acts? (d) What is the mechanical advantage? 6. 1.00 m 30 deg
Calculate the total work done in units of Joules on a 2.1 kilogram weight attached to a vertical spring with spring constant 152 Newton/meter and rest length 0.61 meters, as it moves upward from a distance 0.4 meters below the rest length. You can neglect drag forces. Note: be sure to include the sign of the work (positive = gains KE, negative = loses KE).
Assume that the average number of of points scored in a typical high school basketball game is 60 (total for both theams_ The standard deviation is 20 points. What percentage of games have a total between 55 and 75 points? (Draw histogram to help.)

of each force is 4 N.
Please give me the correct answer.
Q2) Chi-Square Test for Goodness of Fit (10 points) A high school physics teacher wondered if his students in the senior class this year will be more likely to go into STEM (Science, Technology, Engineering, Mathematics) majors than Social Science and Liberal Arts majors. He asked each of his 50 students about their first choice for major on their college applications and conducted a Chi-square test for goodness of fit with an alpha level of .05 to see if the...
