Question

a bullet of mass 50 is shot with velocity 500 m/s it gets embeded in a black at rest which eventually starts moving at 10m/s.find the mass of the block​

Answer 1

Answer:

• Here on earth a bullet will climb at a decelerating speed to apogee. and lose any remaining spin as it redirects towards the ground.
• A 22-250 bullet has a muzzle velocity of approx. 4200 FPS,(2,863 MPH).
• An average falling bullet will reach its terminal velocity around 300 FPS (204 MPH). About 9.5 times slower than the bullet's initial velocity.

Answer 2

Mass of bullet⇨50g⇨0.05kg

Velocity ⇨100m/s

•°•Momentum ⇨0.05×100

Momentum ⇨5kgms-²

Now mass of barrel ⇨x

velocity of barrel⇨60m/s

•°•Momentum ⇨60xkgms-²

We know momentum get conserved

so momentum of bullet = momentum of barrel

•°• 5kgms-² = 6x kgms-²

→6x=5

→x = 0.8kg

Therefore mass of barrel is 0.8kg
