Question

a bullet is moving with a speed of 367m/s when it enters a lump of moist clay. the bullet penetrates a distance of 0.0621m. determine the acceleration of the bullet while moving into the clay. assume uniform acceleration.

Answer 1

\[v ^{2}=u ^{2} +2ad\]Let,
v = final velocity (0)
u = intial velocity (367m/s)
d = 0.0621
Solve for a,
\[0^{2}=367^{2}+2\times a \times 0.0621\]
