Answer:
We have,
Kinetic energy,
K = 1/2 mv^2
Where 'm' is the mass of the object and 'v' is the velocity of linear motion.
Similarly,
Linear momentum,
P = mv
On solving the 2 equations, we get the direct relation between P and K.
K = P^2/2m
Or k is proportional to P^2
It is said that linear Kinetic energy raised by 100%, so new Kinetic energy,
K*= 2 K
To find the new momentum P*,
K∗/K=(P∗/P)2
2K/K=(P∗/P)2
2=(P∗/P)2
P∗=√2P
The momentum increases √2 times.
PLEASE .... MARK BRAINLIEST
hope its clear: )
