Answer» :➥ The potential energy possessed by a cricket BALL = 12.8 JGiven :➤ Mass of a cricket ball (m) = 160 g➤ Height (h) = 8 m➤ Acceleration due to gravity (g) = 10 m/s²To Find :➤ Potential energy possessed by a cricket ball (P.E) = ?Solution :To find the potential energy possessed by a cricket ball, first we need tk convert the mass of a cricket ball (m) GRAM into KG, then after we find the potential energy possessed by a cricket ball from the potential energy formula.◈ Mass (m) = 160 g = 160/1000 = 0.16 kgAs we know that→ P.E = mgh→ P.E = 0.16 × 8 × 10→ P.E = 1.28 × 10→ P.E = 12.8 JHence, the potential energy possessed by a cricket ball is 12.8 J.Some RELATED formulae :⪼ KINETIC energy = ½mv²⪼ Potential energy = mgh⪼ Work done = Force × DisplacementWhere,m is the mass.v is the velocity.g is the acceleration due to gravity.h is the height.━━━━━━━━━━━━━━━━━━━━━ |
