Answer:
jk
Explanation:
Lets decompose the initial velocity into its components:
Vi = 2.25 m/s
Vix = Vi x cos(50)
Viy = Vi x sin(50) = 2.25 x sin(50) = 1.724
Then decompose the final velocity:
Vf = 4.65
Vfx = Vf x cos(120)
Vfy = Vf x sin(120) = 4.65 x sin(120) = 4.027
After that we can use:
Vfy = Viy + ay*t
ay = (Vfy - Viy)/t
ay = (4.027 - 1.724) / 8.33
ay = 0.276

Explanation:
this is because heat always travel's from the warmest object to the coldest. His hands thermal energy is transferred to the ice making the ice round to the same temperature of his hand. This can also be an example of equalibrum.
