Find the absolute value of the change of the gravitational potential energy (gpe) of the puck-earth system from the moment the puck begins to move to the moment it hits the spring. use 0.253 m for the displacement of the puck along the ramp and 9.80 m/s2 for the acceleration due to gravity. assume that the mass of the puck is 0.180 kg.

0.1672 Joules

Explanation:

The gravitational potential energy is given by the following formula

Where,

= = Potential energy

m = mass

g = Gravitational Field Strength

h = Vertical Height

Since the launch is made at an angle of inclination,

our objective of interest is the vertical component of that angle,

that is Sin (\ theta)

Where the angle is

In this way,

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
