A bullet is moving at a speed of 367 m/s when it embeds into a lump of moist clay The bullet penetrates for a distance of 0.0621 m. Determine the acceleration of the bullet while moving into the clay (Assume a uniform acceleration.)

Given:

vi = 367 m/s

vf = 0 m/s

d = 0.0621 m

Find:

a = ??

vf2 = vi2 + 2*a*d

(0 m/s)2 = (367 m/s)2 + 2*(a)*(0.0621 m)

0 m2/s2 = (134689 m2/s2) + (0.1242 m)*a

-134689 m2/s2 = (0.1242 m)*a

(-134689 m2/s2)/(0.1242 m) = a

a = -1.08*106 m /s2

(The - sign indicates that the bullet slowed down.)

Answer 2

Explanation:

-1.08× 10^6 m/s²
