HELP ME What is the gravitational potential energy stored in a church bell with a mass of 60 Kg hanging in a church steeple that is 20 m high? A. 1200 J

B. 1960 J

C. 235,200 J

D. 11, 760 J

A

Explanation:

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.

did anyone actually do this? like if anyone has submitted this i rly need .
