If the linear momentum of a sphere is doubled, its kinetic energy will becomea) twiceb) four timesc) eight timesd) sixteen times |
|
Answer» p = (2*kinetic energy*m)^0.5=> (p2/p1)^2 = k2/k1=> (2/1)^2 = k2/k1=> k2/k1 = 4/1Here, k represents Kinetic energy and p represents momentum.Hence, with doubling of momentum, the kinetic energy becomes four times. Please hit the like button if this helped you. |
