Question

What potential energy would be acquired by Hammer of mass 1 kg when it is raised to 2m? (g = 9.8m /s2)​

Answer 1

Answer:

P.E. = 1*9.8*2

Explanation:

P.E. = mgh

mass=1kg (kg is the required unit so no changes)

g= 9.8m/s^2(given)

h=2m(m is the required unit so no changes)

Putting in the values

P.E.=1kg*9.8(m/s^2)*2m

P.E.=19.6kg*m2/s2

P.E.=19.6 Joule
