Mass of solid cube = 725g = 0.725kg Length of each side = 6.35cm =0.0635 m As volume = length ×length×length Volume= 0.0635×0.0635×0.0635 =0.1905 m³ ρ = m/V ρ= 0.725/0.1905 = 0.138 kg/m³ Answer
Answer: Average acceleration is -2.407 ![\frac{m}{s^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D)
Explanation:
Average acceleration is equal to change in velocity divided by time taken
therefore, ![a=\frac{Vf-Vi}{t}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7BVf-Vi%7D%7Bt%7D)
=> ![a=\frac{37-89}{6}\times \frac{5}{18}\frac{m}{s^{2}} = -2.407 \frac{m}{s^{2}}](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B37-89%7D%7B6%7D%5Ctimes%20%5Cfrac%7B5%7D%7B18%7D%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D%20%3D%20-2.407%20%5Cfrac%7Bm%7D%7Bs%5E%7B2%7D%7D)
