Answer:
Her acceleration was 0.8 m/s².
Explanation:
Given data:
Final speed v₂ = 5.4 m/s
Initial speed v₁= 3.0 m/s
Initial time t₁ = 2 s
Final time t₂ = 5 s
Acceleration = ?
Solution:
acceleration = (v₂- v₁) / (t₂ - t₁)
acceleration = 5.4 - 3 / 5-2
acceleration = 2.4 / 3 = 0.8 m/s²
Answer:
Gold is a relatively dense metal because its atoms have more
protons than atoms of many other metals.
Explanation:
