Answer:
G.P.E = 5.292 Joules
Explanation:
Given the following data;
Mass = 0.6 kg
Height = 0.9 m
To find the gravitational potential energy;
Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
Mathematically, potential energy is given by the formula;
Where,
G.P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
But we know that acceleration due to gravity is equal to 9.8m/s²
G.P.E = 0.6*9.8*0.9
G.P.E = 5.292 Joules
Opposite charges attract
Like charges repel
It would be 5,400N. I hope this helps!
Answer:
No she cannot.
Explanation:
Let 
be the horizontal component of the ball velocity when it's kicked, assume no air resistance, this is a constant. Also let 
be the vertical component of the ball velocity, which is affected by gravity after it's kicked.
The time it takes to travel 95m accross the field is
or 
t is also the time it takes to travel up, and the fall down to the ground, which ultimately stops the motion. So the vertical displacement after time t is 0
where g = -9.8m/s2 in the opposite direction with
Since the total velocity that the goal keeper can give the ball is 30m/s
Let substitute x = 
> 0
We can multiply both sides by x
As 
The solution for this quadratic equation is indefinite
So it's not possible for the goal keeper to do this.
