Answer:
-0.056 is the deceleration
Answer:
The angle of launch is 52.49 Degree.
Explanation:
The Range R and Height H of a thrown object is calculated using the formula,
R=V₀² sin(2φ)/g
H=V₀²sin²(φ)/g
From these equations it can be written,
V₀²=R g/ sin(2φ)
V₀²=H g/ sin²(φ)
These values are equal so it can be written by equating these equations,
R g/sin(2φ)=H g/sin²(φ)
tan(φ)= 2H/R
Given H=72.3 m and R=111 m, the angle of launch is,
tan(φ)= 2*72.3/111
φ= 52.49 Degree.

the Republic of South Africa country is being described by these statements
<u>Explanation:</u>
South Africa has the highest amount of people living with HIV/AIDS in the world. It was initially identified in 1982. The ANC came to power in 1994 after ten years of National Party inaction concerning AIDS. The ANC although took province with a formidable strategy, on record at least, for speaking HIV/AIDS.
A National AIDS Convention of South Africa (NACOSA), first gathered in 1992, brought collectively the ANC, the ANC-aligned United Democratic Front, and the National Party government’s ministry of health, to develop a comprehensive 1994 national AIDS plan based on robust projections: ‘HIV/AIDS is emerging as a major public health problem, with over 2,000 reported cases at the end of 1993, and 500,000 people infected with HIV’.
In most calendar years there are two lunar eclipses; in some years one or three or none occur. Solar eclipses occur two to five times a year, five being exceptional
