Question

Calculate the gravitational potential energy a 1kg ball has when thrown 3 m into the air. The gravitational field strength on earth is 9.8 N/kg

Answer 1

P.E.=29.4Nm

Step-by-step explanation:

given data

m=1kg

h=3m

g=9.8m/s²

to find

gravitational potential energy=P.E.=?

solution

P.E.=mgh

PUTTING VALUES

P.E.=1kg×9.8m/s²×3m

P.E.=29.4Nm
