Answer #1

The horizontal range is related to initial velocity u and angle of projection with horizontal as

In the first case = 26o and in the second case = 28o.Then

and

and

In the second case the horizontal range is more because Horizontal Range increases with increase in angle made by the projectile with horizontal until 45o.

PROBLEM A long jumper (see figure) leaves the ground at an angle of 20.0°to the horizontal and at a speed of 11.0 m/s. (a) How long does it take for him to reach maximum height? (b) What is the maximum height? (c) How far does he jump? (Assume his motion is equivalent to that of a particle, disregarding the motion of his arms and legs.) (d) Use the proper equation to find the maximum height he reaches. STRATEGY Again, we...

Assume that the initials of any person are written using only the 26 uppercase letters and are at least two letters long (that everyone has at least a first name and a last name) and at most five letters long (e.g., someone might have three middle names, in which case they would have five initials). How many different strings of initials (of length two, three, four, or five) are there in which not all the letters are the same? Note:...

Plot entire travelling paths of two projectiles, i.e., two angry birds, on x-y plane, assuming they were thrown at the origin. The first angry bird was thrown with the initial velocity, vo,1 = 2 m/s, and the angle of the initial velocity from the horizontal plane, (theta),1 = (pi)/4, while the other was thrown with vo,2 = 10 m/s and (theta),2 = (pi)/6. Make sure that you plot two paths in the same plot with different line types, colors, and...

I am a little confused with two similarly looking to me questions that have different explanations and I’d like to understand why. First question is this: “Which method does less work against gravity: carrying a 1 kg weight up 50 m by taking the stairs or taking the elevator. Explain”. Here we say the work is the same and that the path traveled doesn’t matter and use w=mgh where H is just a vertical component. The second question is “a...

Consider a two countries, Portugal and England, that produce two goods, wine and cheese, with only one factor of production, Labor. In Portugal, one unit of labor can produce 1 unit of wine or 1 unit of cheese. In England, one unit of labor can produce 1 unit of wine or 2 of cheese. There are 100 units of labor in Portugal, and 100 in England. Countries share the same tastes, and there is perfect competition. 1) Fill in the...

6. An investment banking firm was considering two spreadsheet software for possible use in its large data analysis operations. A sample of 20 typical analysis problems were carried out using both software on the firm’s standard personal computer. The time in minutes needed to load the data, program the spreadsheet calculations, carry out the analysis, and print the results was recorded for each problem for each software. The data for software A are stored in column 1 of the Excel...

4. A sociologist cites a study showing that, in a particular parish, the amount of time preschool children ages 3–5 spend watching TV is 22.6 hours per week, with a standard deviation of 6.1 hours. A second researcher doubts these findings, believing that the actual figure is higher. To attempt to resolve the question, a simple random sample of 60 preschool children is chosen, and their TV watching habits are measured by having their parents keep a daily log of...
