We are given –

  • Gravitational potential Energy [tex]\sf E_k[/tex]= 116.62 J
  • Hight, h = 85 m
  • Gravitational acceleration, g =9.8 m/s ²
  • Mass,m =?

Substituting values–

[tex]\qquad[/tex][tex]\purple{ \bf \twoheadrightarrow E_k = mgh} [/tex]

[tex]\qquad[/tex][tex] \bf \twoheadrightarrow E_k = m \times 9.8 \times 85[/tex]

[tex]\qquad[/tex][tex] \bf \twoheadrightarrow 116.62 = m \times 833[/tex]

[tex]\qquad[/tex][tex]\bf \twoheadrightarrow m \times 833 = 116.62 [/tex]

[tex]\qquad[/tex][tex] \bf \twoheadrightarrow m =\cancel{ \dfrac{116.62}{833}}[/tex]

[tex]\qquad[/tex][tex]\purple{ \bf \twoheadrightarrow m = 0.14\: kg} [/tex]

  • Henceforth , mass of ball 0.14 kg.
