Question

As shown in the figure below, bullet is fired passes through piece target paper suspended by a massless string.

As shown in the figure below, a bullet is fired at and passes through a piece of target paper suspended by a massless string. The bullet has a mass (0.536)v after passing through the target. M th) Alter collision Before collision The collision is inelastic and during the collision, the amount of energy lost is equal to a fraction ((0.263)KEec) of the kinetic energy of the bullet bef speed of the target the instant after the collision in terms of the mass m of the bullet and speed of the bullet before the collision (Express your ans V- v M
