Question

a bullet is moving with a speed of 150m/s when it embedds into a lump of moist clay.it penetrates for a distance of 0.06 m. determine the acceleration of the bullet while moving into the clay

​

Answer 1

Answer:

187500m)s^2

Explanation:

we have,

u=150m/s

v=0m/s (as it stops after getting penetrated)

s=0.06m

so from third equation of motion,

v^2=u^2+2as

0=150^2-2a×0.06. (as it is in retarding motion)

or, 0.12a=150×150

or, a=150×150/0.12

or, a= 187500m/s^2
