Question

A glass can bear a maximum pressure of 4 - 10% Pa.
If we horizontally shoot a bullies of face area 0.05
em- and mass 20 g from a gun with a constant
velocity of 200 ms and time of contact with glass is
0.2s then can the bullet break the glass? Assume
the bullet moves with constant velocity and stops
after it hits the glass​

Answer 1

Answer:

Explanation:

PV=nRT

∴PαT

when P=4×10  

5

Pa⇒T=300K

∴ when P=8×10  

5

Pa

T=600K
