Question

Q. A bullet is fired on a wall with a velocity of 100m/s. If the bullet stops in 10 seconds, then find the retardation produced by the wall.

Answer 1

Answer:

given u=100m/s

v=om/s

t=10s

we know that

v=u +at

=>o=100+a *10

=>-100/10=a

=>a=-10

Step-by-step explanation:

here a is retardation =acceleration

and negative sign is due to retardation acceleration
