It is is real because potential energy is stored inside gravitational energy.
Answer: c. displacement
Explanation:
Let's begin by stating clear that motion is the change of position of a body at a certain time. So, during this motion, the body will have a trajectory and a displacement.
In the specific case of the displacement, it is defined as the distance in a straight line between the initial and final position (is a vector magnitude).
Therefore:
Displacement s the the change in position relative to an initial location.
Work = Force x displacement
Force = mass x gravitational acceleration
Force = 60 x 9.81 = 588.6N
Work = 588.6 x 0.12m =70.632 J
Answer:
11.9051g
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.8 m/s²
Absolute value of the (negative) average acceleration is 116.67 m/s²
The deceleration was 11.9051g
