Question

What is the potential energy of a 0.5 kg ball sitting on a table 1 meter

above the ground?
A. 98 J
B. 4.9 J
C. 9.8 J
D. 0.5 J

Answer 1

Hey!!

Mass=0.5kg

H=1 meter

Gravity=9.8m/s^2

Now,

Potential energy=m*g*h

= 0.5*9.8*1

=4.9 J

The right answer is 4.9 Joule.

Hope it helps

Good luck on your assignment
