Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimu
m necessary. find the magnitude of the frictional force between the person and the wall.
2 answers:
In the magnitud is in good
Answer:
friction force must be equal to the magnitude of weight of the object
Explanation:
When the object is stuck against the wall
then we will have

also we know that

so if the block is at rest and not sliding then in vertical direction the force must be balanced
so here we can say

so friction force must be equal to the magnitude of weight of the object

Answer:
F = 6,000 N
Explanation:
F = m × a
F = 2,000 × 3
F = 6,000 kg m/s²
F = 6,000 N

Answer:
yes i think that inner planets should be explored because if we ever find new life or are able to live there then i think its worth takeing a risk.
Explanation:
- Mass=1167kg
- Initial velocity=u=10m/s
- Acceleration=a=4m/s^2
- Work done=105J=W
- Final velocity=v=?
- Force=F
- Distance=d

Answer:
2.96×10⁸ m/s
Explanation:
Speed = distance / time
v = (2 × 3.85×10⁸ m) / (2.60 s)
v = 2.96×10⁸ m/s
