mass ( m ) = 5 kg
height ( h ) = 20cm
acceleration due to gravity ( g ) = 9.8 m/s^2
as we know that
potential energy = mgh
= 5 × 20 × 9.8
= 100 × 9.8
= 980 J
so potential energy is 980 J
height ( h ) = 20cm
acceleration due to gravity ( g ) = 9.8 m/s^2
as we know that
potential energy = mgh
= 5 × 20 × 9.8
= 100 × 9.8
= 980 J
so potential energy is 980 J
