a ball falls from a tall bridge the ball has a mass of 0.15 kg the air density is 1.225 kg/m^2 the balls coefficient of drag is 0.007 what is the balls terminal velocity?
A 363m/s
B 30.4 m/s
C 164 m/s
D 402 m/s
The formula for calculating terminal velocity is given by:
v = √[(2mg)/(ρACd)]
Where:
v = terminal velocity (m/s)
m = mass of the ball (kg)
g = acceleration due to gravity (9.8 m/s^2)
ρ = air density (kg/m^3)
A = projected area of the ball (m^2)
Cd = coefficient of drag
In this case, the mass of the ball (m) is 0.15 kg, the air density (ρ) is 1.225 kg/m^3, and the coefficient of drag (Cd) is 0.007. We need to find the terminal velocity (v).
To calculate the projected area (A) of the ball, we need more information about its shape. Since the shape of the ball is not given, we cannot calculate the terminal velocity. Therefore, the answer cannot be determined with the information provided.
