Hey there!
There are two different forms of mechanical energy: Kinetic energy and Potential energy.
Kinetic energy is created by an object's motion.
Potential energy is created by an object's position or its configuration.
Thank you!
Answer: The highest point upwards and lowest point downward
Explanation:
Amplitude is the point of maximum displacement.
Your question is incomplete.
A mass of 148 g stretches a spring 13 cm. The mass is set in motion from its equlibrium position with a downward velocity of 10 cm/s and no damping is applied. a. Determine the position u of the mass at any time t. Use 9.8 m/s as the acceleration due to gravity. Pay close attention to the units. u(t) = m b.
Answer:
u(t) = y = 0.0115Cos(8.7t)
Explanation:
Given m = 148g = 0.148kg
x = 13cm = 0.13m = stretched distance
vy = 10cm/s = 0.1m/s = initial downward velocity
g = 9.8m/s²
k = mg/x = 0.148×9.8/0.13 = 11.2N/m = spring constant
ω = √(k/m) = √(11.2/0.148) = 8.7rad/s = angular frequency
A = √(yo² +voy²/ω²) = √(0² +0.1²/8.7²)
A = 0.0115m
y = ACos(ωt) = position with respect to time for a zero phase angle
y = 0.0115Cos(8.7t)
Where A = the amplitude of the motion.

Answer:
U=244608J
Explanation:
The equation of gravitational potential energy is <em>U=mg(h-h_0)</em>, where <em>h_0 </em>can be any reference we choose. In this case, the reference is set at an altitude of 2350m, so any gravitational potential energy above this point will be positive and below it will be negative.
For our values then we have:
