Answer 1

Answer:

mass m kg

let, weight of the man on earth W

1

weight of the man on planet A W

2

given: W

2

=

2

W

1

or mg

′

=

2

mg

or g

′

=

2

g

potential energy used by him to jump height of 0.4m on earth is 0.4mg.

if he apply same potential energy on planet A with acceleration due to gravity g

′

he would move a height h

′

so,mgh=mg

′

h

′

since,

2

g

=g

′

g×0.4=

2

g

h

′

so, h

′

=0.8m

hence, he can jump on the planet A up to height of 0.8m.
