I think the correct answer from the choices listed above is option A. In a position vs. time graph depicting the motion of two different objects, the point at which the lines intersect is where the objects <span>have the same position. Hope this answers the question. Have a nice day.</span>
Answer:
both magnitude and direction
Explanation:
The worker's pull on the handle of the cart is best described as the force having both magnitude and direction.
- This is a vector quantity
- The force is channeled to move the cart in a specific direction.
- Also, the pull on the cart can be quantified, and so it have magnitude.
- Most physical properties either have magnitude or direction or both.
In this case, the worker is pulling the cart towards a specified direction.
Therefore, the fitting choice is both magnitude and direction.
Answer:
Explanation:
As we know that the that the Astronaut dropped a stone on the surface of the planet takes 0.420 s to fall a distance of d = 1.90 m
so we will have
now we know that the acceleration due to gravity is given as
so we will have
Answer:
8
Explanation:
Finding time= t=change in velocity or distance/acceleration
so 32/9.5-5.5
32/4
8
There are several information's already given in the question. Based on those given information's the answer can be easily deduced.
First angle of depression = 18°33'
= [18 + (33/60)] degree
= 18.55 degrees
Second angle of depression = 51°33'
= [51 + (33/60)] degrees
= 51.55 degrees
Height of the lighthouse = 200 feet
Then
Distance traveled by the boat from when it
was first noticed until it stopped = (200/tan 18.55) - (200/tan 51.55)
= (200/0.3356) - (200/1.2594)
= 594.95 - 158.81
= 436.14 feet
I hope the procedure is clear enough for you to understand.
