Question

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

Answer 1

Answer:

3.2 m

Explanation:

we know

Hmax = V²/2g

= 8² / 2*10 = 3.2

Answer 2

Answer:

The ball will get upto the height of 3.26 meters.

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 :

$v^2-u^2=2as$

$(0 m/s)^2-(8 m/s)^2=2\times (-g)\times s$

$(0 m/s)^2-(8 m/s)^2=2\times (-9.8)\times s$

$s=\frac{(-8 m/s)^2}{2\times -9.8 m/s^2}=3.26 m$

The ball will get upto the height of 3.26 meters.
