Question

a bullet of mass 5g travelling with a velocity of 18km/h penetrates a wooden block and comes to rest in 0.01sec find
a) the distance through which it penetrates in the wooden block
b)the value of the retarding force of the block​

Answer 1

Answer:

to 6.0cm . Then the average force applied by the bullet on the block is: ... A bullet of 5g, travelling at a speed of 100m/s penetrates a wooden block up to 6 .0cm. ... Distance covered in block S=6 cm=0.06 m.

Top answer

Initial kinetic energy K.Ei = 12mv^2 = 12(0.005)(100)^2 = 25 J Final velocity of bullet vf = 0 So, final kinetic energy K.Ef = 0 Distance covered in block ... More
