Answer:
The range is maximum when the angle of projection is 45 degree.
Explanation:
The formula for the horizontal range of the projectile is given by
The range should be maximum if the value of Sin2θ is maximum.
The maximum value of Sin2θ is 1.
It means 2θ = 90
θ = 45
Thus, the range is maximum when the angle of projection is 45 degree.
If the angle of projection is 0 degree
R = 0
It means the horizontal distance covered by the projectile is zero, it can move in vertical direction.
If the angle of projection is 30 degree.
R = 0.088u^2
If the angle of projection is 45 degree.
R = u^2 / g
The mass of an electron, me, 9.11 × 10⁻³¹ kilograms shows there are 3 important numbers in them, namely numbers 9, 1, and 1
<h3><em>Further explanation</em></h3>Significant numbers are obtained from measurement results of exact numbers and the last number estimated
This is called significant numbers
the scientific notation can be described as:
a, ... x 10ⁿ
a, ... called a significant number
10ⁿ is called a big order
Rules for significant numbers in general:
- 1. All non-zero numbers are significant numbers
- 2. a zero which is located between two non-zero numbers including a significant number
- 3. all zeros are located in the final row written behind the decimal point of the include significant number
- 4. zero decimal point is the not significant number
From the numbers known in the question amounting to 9.11 × 10⁻³¹ kilograms shows there are 3 important numbers in them,(symbol a, before a big order ,called a significant number) namely numbers 9, 1, and 1
