Answer:
clockwise torque is due to weight of the person + weight of the ladder
Explanation:
As we know that the forces that act on the ladder is given as
1) friction force
2) Normal force at the ends of the ladder
3) Weight of the person standing on the ladder
4) Weight of the ladder
So here we know that our reference point is at the bottom position of the ladder
So we will have
Torque due to weight of the person and weight of the ladder is counter balanced by the torque due to normal force and torque due to friction force
So here we have
clockwise torque is due to weight of the person + weight of the ladder
The height of the roof is <u>3.57m</u>
Let the drops fall at a rate of 1 drop per t seconds. The first drop takes 5t seconds to reach the ground. The second drop takes 4t seconds to reach the bottom of the 1.00 m window, while the 3rd drop takes 3t s to reach the top of the window.
Calculate the distances traveled by the second and the third drops s₂ and s₃, which start from rest from the roof of the building.
The length of the window s is given by,
The first drop is at the bottom and it takes 5t seconds to reach down.
The height of the roof h is the distance traveled by the first drop and is given by,
the height of the roof is 3.57 m
Answer:
The position, speed, direction and acceleration
I think your second figure should be 6km/hour if that is the case then this is the answer.
Answer
A. Negative. this is because your speed is reducing which means you are decelerating or rather going at a negative (acceleration).
