Ek = 1/2 × m × v² ;
Ek...kinetic energy
m...mass
v...velocity
If we double the velocity,then Ek = 1/2 × m × (2×v)² = 1/2 × m × 4×v² = 2×m×v²
<em />
so the correct answer is C
Answer: Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
We will either die cause with no gravity then we cant breathe or we may die due to the fact were in space or maybe be frozen due to the fact we will be 500k feet up air
Answer:
v = 2.41 m/s
Explanation:
Here net force on the Skater + snowball is zero
so here we can use momentum conservation for skater + snowball
now we have
so the final speed of skater will be 2.41 m/s
