A soccer ball is kicked horizontally off a bridge with a height of 36m. The ball travels 25m horizontally before it hits the pavement below. What was the soccer ball’s speed when it was first kicked?

The initial velocity at which the ball is kicked is 9.22 m/s

Explanation:

Given

bridge height, h = 36 m

Horizontal distance at which ball falls, = 25 m

Firstly, we have to find the time taken by ball to reach vertically. It is calculated using formula,

d = t +

where d is vertical distance, d = h and a is acceleration due to gravity, a = g = 9.8 m/. Also initially ball is at rest, hence = 0. Substituting the values in the formula, we get

-36 = 0 + (-)   (negative sign is because the object moves downward)

= 7.347

t =

 = 2.711 s

To find: initial velocity

We know that horizontal velocity is derived from horizontal distance and time:

=

     =

     = 9.22 m/s

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
