Minimum Initial Velocity Calculator:
Enter the values of Accelaration of gravity G(m/s2), Height H(m) & Angle of launch a(deg) to determine the value of Minimum Initial Velocity Vmin(m/s).
Minimum Initial Velocity Formula:
The Minimum Initial Velocity Vmin(m/s) in meter per second is equal to the SQRT of the Value of 2 into multiply the Accelaration of gravity G(m/s2) in meter per second square and Height H(m) in meter and then divided by the Sin Angle of launch a(deg) in degree.
The Equation of Minimum Initial Velocity can be writtern as,
Vmin(m/s) = SQRT ( 2 * G(m/s2) * H(m) / Sin2 a(deg) )
Here,
Vmin(m/s) = Minimum Initial Velocity in meter per second
G(m/s2) = Accelaration of gravity in meter per second square
H(m) = Height in meter
a(deg) = Angle of launch in degree
Minimum Initial Velocity Calculation :</u.
1)Calculate the Minimum Initial Velocity and given for gravity = 9.81m/s2 , Height = 40m , Angle of launch = 45degree.
Answer
Vmin = √( 2 * G * H / Sin2 ( a ) )
Vmin = √ ( 2 * 9.81 * 40 / Sin2 ( 40 ) )
Vmin = 37.59m/s.
2)Calculate the Height and given for gravity = 9.81m/s2 , Angle of launch = 45degree , Minimum Initial Velocity = 37.59m/s.
Answer
Vmin = √( 2 * G * H / Sin2 ( a ) )
37.59 = √ ( 2 * 9.81 * H / Sin2 ( 40 ) )
H = 40m.
