Answer:
in the direction of motion of Jacob
Explanation:
Given:
mass of Jacob, 
velocity of Jacob, 
mass of Ethan, 
velocity of Ethan, 
Now using the conservation of linear momentum for the case:
(When the two masses in motion combine to form one after the collision then they will move together in the direction of the greater momentum.)
in the direction of motion of Jacob as it was assumed to be positive.
Answer:
1. In a coal-fired power plant, chemical energy is first converted to thermal energy. TRUE.
The chemical energy in the coal is converted to thermal energy when the coal is burnt to produce steam.
2. In a coal-fired power plant, approximately 2/5 of original energy in the coal is lost to heat. FALSE.
Approximately 3/5 of the original energy is lost not 2/5 so this statement is false.
3. The molecules in cold air move faster than in hot air. FALSE.
Molecules with more heat move faster than molecules with less. Molecules in cold air therefore, will move slower than molecules in hot air.

Answer:
268.22m/s
Explanation:
Given;
10mile/min to m/s
We need to convert between the two units;
Using the dimensions;
1 mile = 1609.34m
60s = 1min
Now;
10 x 
x 
x 
= 268.22m/s
