A golf ball is hit from a Sandtrap 1.5 m below ground level with an initial velocity of 50 m/s what was the highest point of the ball?

1) A7 ft tall person is walking away from a 20 ft tall lamppost at a rate of 5 ft/sec. Assume the scenario can be modeled with right triangles. At what rate is the length of the person's shadow changing when the person is 16 ft from the lamppost? 20 ft 7 ft tall 5 ft/sec distance from lampost - shadow- length 2) Identify all known and unknown variables and constants that are referenced in the word problem. For example, you could say "x = the distance from earth to mars, the radius of earth is a constant, and dx/dt = rate of change in the distance from earth to mars. The problem gives us that dx/dt = -3 when x = 7." 3) Which of the values in part 2 is the question asking you to solve for? For example, you could say "It is asking to solve for dy/dt." 4) What formulas/equations would you use to help you solve is equation and why? For example, you could say "I'd use the formula A = 0.5BH for the area of a triangle because those are the relevant equations quantities involved in the problem.…

2. A horizontal curve on a two-lane highway (10ft lanes) is designed for 50mi/h with a 6% superelevation. The central angle of the curve is 35 degrees and the PI is at station 482+72. What is the station of the PT and how many feet have to be cleared from the lane's shoulder edge to provide adequate stopping sight distance?

The projectile is thrown at the angle of 45 degrees with the initial velocityof 1 meter per second. The free-fall acceleration is 9.8 meters per second. What is the distance between the point where the projectile was thrown and where it would land?

The population mean of water consumption is 120.3 gallons with a standard deviation of 10.0 gallons. Test the claim at the 0.10 significance level that the average amount of water consumed is not 125 gallons with a sample size of 100 residences. What is the X? QUESTION 3
