Question

A bullet is moving at a velocity of 425 m/s when it strikes a piece of moist clay. The bullet
penetrates for a distance of 0.0750 m. Determine the acceleration of the bullet while
moving for a distance of 0.0750 m. Determine the acceleration of the bullet while moving
into the clay. (Assume a uniform acceleration.)
a. -2.41 x 108 m/s2
b. -1.95 x 106 m/s2
C. -1.20 x 105 m/s2
d. None of the above

Answer 1

Answer:

d. None of the above

Explanation:

v² = u² + 2as

a = (v² - u²) / 2s

a = (0² - 425²) / (2(0.0750))

a = -1.2041666666666666666666666666667e+6

a = -1.20 x 10^6 m/s²

where the negative sign denotes acceleration opposing original velocity u.
