Question

if you apply 1joule of energy to lift a book of 0.5 kg how high it will rise (given=10m/s^2)​

Answer 1

Answer:

0.2m

Explanation:

we know that,P.E=mgh

1J=(0.5)(10)h

h=0.2m

Answer 2

Answer:

0.2m

Explanation:

f = maf=ma

0.5×a

0.5×g. g=10m/s2

f= 5 newtons

work = force \times displacementwork=force×displacement

1 Joule=5 Newton's× Displacement

Displacement=1/5

Displacement=0.2 meter
