Question

to what height will a 250g soccer ball rise to if it is kicked directly upwards at 8 meters per second​

Answer 1

3.2 m

Step-by-step explanation:

we know

Hmax = V²/2g

= 8² / 2*10 = 3.2

Answer 2

The ball will get upto the height of 3.26 meters.

Step-by-step explanation:

Initial velocity of the ball = u = 8 m/s

final velocity of the ball = v = 0 m/s ( upward)

Acceleration due to gravity ,a= -g =
`-9.8 m/s^2`

Height of the ball when kicked = s

Using third equation of motion :

`v^2-u^2=2as`

`(0 m/s)^2-(8 m/s)^2=2* (-g)* s`

`(0 m/s)^2-(8 m/s)^2=2* (-9.8)* s`

`s=((-8 m/s)^2)/(2* -9.8 m/s^2)=3.26 m`

The ball will get upto the height of 3.26 meters.
