Answer:
g = 0.4 m/s²
Explanation:
Given the following data;
Height = 5 meters
Time = 5 seconds
To find the acceleration due to gravity (g) on the planet;
Mathematically, the maximum height of an object is given by the formula;
H = ½gt²
Where;
H is the height measured in meters.
g is the acceleration due to gravity.
t is time measured in seconds.
Substituting into the formula, we have;
5 = ½ * g * 5²
5 = 0.5 * g * 25
5 = 12.5 * g
g = 5/12.5
g = 0.4 m/s²
Im not so sure but it should be the
instantaneous speed
Explanation:
The energy stored in an elastic objects as a result of deformation is called elastic potential energy. The energy stored in a spring is given by :

Where
k = spring constant
x = compression or stretching in an spring
While gravitational potential energy is given by :
PE = mgh
where
m = mass
g = acceleration due to gravity
h = height from ground
So, the factor affecting elastic potential energy but not gravitational potential energy is " spring constant ".
When a force acts (pushes or pulls) on an object, it changes the object's speed or direction (in other words, makes it accelerate). The bigger the force, the more the object accelerates. When a force acts on an object, there's an equal force (called a reaction) acting in the opposite direction.
