Question

how high should a hammer of mass 3 kg be raisedso that it aquires a potential energy of 45 j?​

Answer 1

Answer:

The hammer should be kept 1.5m high

Explanation:

Potential energy gained by a body at topmost point is given as mass(m)*acceleration due to gravity (g)*height(h)

Potential energy=m*g*h

45=3*10*h

Therefore from here height comes out to be 1.5 m
