Answer:
276.62 m/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 9.81 m/s² (positive downward and negative upward)
Equation of motion
<u>Neglecting air drag</u> the velocity of the spherical drop would be 276.62 m/s
Answer:3.67 s
Explanation:
Given
Ball is thrown with an initial velocity of
As the ball moves upward it experience a declaration due to gravity which will slow down the ball
using
where v=final velocity
u=initial velocity
a=acceleration
t=time
Here
