Answer:
2.88×10⁻⁹ s
2.40×10¹⁵ m/s²
Explanation:
Given:
v₀ = 12300 m/s
v = 6.92×10⁶ m/s
Δx = 0.997 cm = 0.00997 m
Part 1) Find: t
Δx = ½ (v + v₀)t
0.00997 m = ½ (6.92×10⁶ m/s + 12300 m/s) t
t = 2.88×10⁻⁹ s
Part 2) Find: a
(6.92×10⁶ m/s)² = (12300 m/s)² + 2a (0.00997 m)
a = 2.40×10¹⁵ m/s²
Answer:
1. Since the carpet is softer than the concrete and the force of impact is reduced by the extended time of impact.
Explanation.
The carpet provides energy dissipation over a porous layer of material.
Because of this, the carpet behaves as if it was a spring and a dashpot.
The spring absorbs the kinetic energy, and the dashpot dissipates the energy.
The ticker the carpet, the better the energy dissipation will be.
For a small stress, the relation between stress and strain is linear. ... Shear strain is the deformation of an object or medium under shear stress. The shear modulus is the elastic modulus in this case. Shear stress is caused by forces acting along the object's two parallel surfaces.
