In the above diagram, the block is at static equilibrium on the ground. What is the value of the force exerted by the ground on the block if the force due to gravity is 12 newtons? A.
20 newtons
B.
12 newtons
C.
-12 newtons
D.
-20 newtons
E.
0 newtons

The answer my dear friends is B I made a 100

B. 12 newtons

Took this before :3

Goodluck!<3

The answer is B.

Explanation:

u=13

v=30

s/t=u+1\2at

=13+431/2

=13+265.5

=278.5

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
