Answer:
c. 0.71 [s]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 0 (because when the ball reaches the top, there is no movement)
Vo = initial velocity = 7 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time [s]
Note: The negative sign of the equation means that the movement is againts the direction of the gravity acceleration.
Answer:
No
Explanation:
We know that
Rationality in 3D flow is given as follows
If ω is equal to zero then flow will be irrotational and if ω is not equal to zero then flow will be rotational .
So if flow is ir-rotational it means that the component of ω in x-direction,in y-direction and in z-direction direction should be zero.
So it is not necessarily that 3D parallel flow will be irrotaional.
