Answer:
v=30 m/s
Explanation:
h - height
g - acceleration due to gravity=10
t - time
v- velocity
45 = 5t²
t² = 9
t=3 seconds
v=g×t
v=10×3
v=30 m/s
In which position would an object have a greater amount of potential energy
2 answers:
Answer:
At the maximum height
Explanation:
The gravitational potential energy of an object is the energy possessed by the object due to its position in the gravitational field.
Mathematically, it is given by:
where
m is the mass of the object
g is the acceleration due to gravity
h is the height of the object relative to the ground
From the formula, we see that the potential energy is directly proportional to the height of the object above the ground: therefore, the larger the value of h, the larger the potential energy of the object.
Therefore, the object has the maximum potential energy when it is at the highest position above the ground.
