Answer:
= 238N
Explanation:
mass = 0.14g = 14 × 10⁻⁵kg
initial velocity = 218m/s
final velocity = 0
penetration depth (distance) = 14mm = 14 × 10⁻³m
v²(final) = v²(initial) + 2aΔx
0² = (218)² + 2(14 × 10⁻³)a
a = -(218)² / 2(14 × 10⁻³)
a = 16.97 × 10⁵m/s²
F = ma
= (14 × 10⁻⁵)(16.97 × 10⁵)
= 237.58N
≅ 238N
