Ignoring air resistance, how much farther would it travel on the moon than on earth?
III On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a golf club improvised from a tool. The free-fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 25 m/s at an angle 30° above the horizontal. […]
What was the bullet’s speed as it left the barrel?
III A rifle is aimed horizontally at a target 50 m away. The bullet hits the target 2.0 cm below the aim point. What was the bullet’s flight time? What was the bullet’s speed as it left the barrel?
What was the vertical component of Jill’s velocity?
II Jack and Jill ran up the hill at 3.0 m/s. The horizontal component of Jill’s velocity vector was 2.5 m/s. What was the angle of the hill? What was the vertical component of Jill’s velocity?
Identify the conversation Alexander is participating in about race, criminal justice, and mass incarceration.
For this journal entry, you will read and reflect upon “The New Jim Crow” by Michelle Alexander in They Say,(Ch. 20). In order to successfully complete this journal entry, you will need to identify the conversation Alexander is participating in about race, criminal justice, and mass incarceration. You should use the templates we have learned […]
What is the average discharge per unit width at x = 525 ft (in units of gal/ft/d)?
The unconfined aquifer shown below is situated between two surface water features. The aquifer overlies impermeable bedrock (elevation of 90 ft) and has a hydraulic conductivity of 46 ft/d. Surface water feature 1 has a water elevation of 156.3 ft and surface water feature 2 has a water elevation of 149.0 ft. The distance between […]
What is a minimal number of wires counted from 70 a cable must have in order to maintain the reliability of the cable (and thus of the system) to at least 0.98?
1 Explain in Example 5.8 (Chapter I, pages 45-46) of the Lecture Notes (a) how A was obtained and (b) what went wrong with the Poisson approximation. (5 pts) Problem 2 is computational, and it should be rendered using the R-programming (no other language or tool). Also, your work must be rendered independently, without any […]
