Answer:
11760N
Explanation:If the boulder is at rest and not going up or down we would take the 1200 kg and multiply it by 9.8 because
(sum)F = ma and since a is 0 the equation goes to
Fn - mg= 0 an that simplifies to
Fn=mg
The normal force points upward and is 11,760 N
Step-by-step explanation:
Resting on the ground = upward
1200 * 9.8 = 11, 760
