metals are conductors, meaning that heat travels through it better than insulators such as plastic (commonly used for pan handles)
Therefore, to avoid the heat burning hands, most pans don't have metal handles.
Answer:
Sliding friction is the force that sliding objects experience
Explanation:
Answer:
0.37 m/s to the left
Explanation:
Momentum is conserved. Initial momentum = final momentum.
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
Initially, both the fisherman/boat and the package are at rest.
0 = m₁ v₁ + m₂ v₂
Plugging in values and solving:
0 = (82 kg + 112 kg) v + (15 kg) (4.8 m/s)
v = -0.37 m/s
The boat's velocity is 0.37 m/s to the left.
