Question

a ball is kicked on level ground with a speed of 30 m/s at angle of 40 degrees above horizontal g Find the minimum velocity of the ball during its flight

Answer 1

The minimum velocity of the ball during its flight is 22.98 m/s.

Step-by-step explanation:

The velocity of the ball v = 30 m/s

The angle it makes with the horizontal ∅ = 40°

The minimum velocity of the ball during flight will be the horizontal axis component of the velocity, as acceleration is zero on this axis.

`V_(x)` = v cos ∅

`V_(x)` = 30 cos 40°

`V_(x)` = 30 x 0.766 = 22.98 m/s
