A golfer hits his approach shot at an angle of 0 = 51.5°, giving the ball an initial speed of vo = 38.3 m/s (see figure below). The ball lands on the elevated green,Yf= 5.9 m above the initial position near the hole, and stops immediately.%3D(a) How much time passed while the ball was in the air?(b) How far did the ball travel horizontally before landing?(c) What was the peak height reached by the ball?

Concept - use equation of kinematics in horizontal and vertical direction separately to find the…

A chemical storage tank ruptures at a point 2 m hove the ground. Chemical leaves the tank in a jet inclined at 15 degrees to the horizontal, travelling at 10 m/s. If the flight of the chemical is ballistic and effects of air resistance are ignored, how far from the base of the tank does the jet reach? (Take g = 9.8 m/S^2). (A) 9.23 m (B) 5.10 m (C) There is not enough information to calculate the answer D) 7.61 m
A steel wire connects two trains at rest on the same track. The wire will snapif it is stretched by as much as 1 percent. The trains begin to accelerate in such away that their velocities, as measured in the ground frame, are always equal.Eventually, the wire snaps. Explain carefully why this happens. How fast are thetrains moving when the wire snaps?
1. Assuming that there are no heat effects and no frictional effects,find the kinetic energy and speed of a 3220lb body after it falls 778 ft from rest. Start with the steady flow equation, deleting energy terms which are irrelevant. Draw a figure or FBD that will support the problem. Explain each step by step formula.

A particle is projected from a horizontal plane and has an initial speed of 50m/s at an angle of 30 degrees above the horizontal. For how long is the particle at least 20 m above the level of the plane? Hint: You may use the formulas for the horizontal x(t) and vertical y(t) displacement of the particle: x(t) = ucos(α)t, y(t) - usin(α)t - ½gt2 , g = 10m/sec2.
A river reach had a flood wave passing through it. At a given instant the storage of water in the reach was estimated as 15.5 ha.m. What would be the storage in the reach after an interval of 3 hours if the average inflow and outflow during the time period are 14.2 m3/sec and 10.6 m3/sec respectively.
What is the maximum power generated by the wind farm with wind speed of 4 m/s? Typical wind turbines have rotor diameters from 40 m to 90 m (Assume increment of 5 m for this problem)-40 m is 80% efficient and efficiency decreases by 5% for every 5 m increase in diameter (i.e. 45 m=75%, 50=70...)-The ridge is 10 km long and wind turbines will be spaced in a single row. •Power in the wind per unit area of circular area is 1/2ρv3W/m2 (v is the wind speed, ρ is 1.3 kg/m3 for air) •Wind turbines cannot be spaced closer than 5 times its diameter without loosing power also there are no partial turbines.
