Question

8. Consider a block of mass 2 kg kept at height of 4 m above the ground level. What will be the potential energy of the block if (g = 10 m/s2) : a. Potential energy is taken as zero at ground level. b. Potential energy is taken as zero at height of 2 m above the ground leve

Answer 1

m = 2kg

h = 4m

a) PE = mgh

   PE = 2*10*4

   PE = 80J

b) PE = mgh

    PE = 2*10*(4-2)

    PE = 40J
