Answer:
Horizontal component,
Explanation:
It is given that,
Displacement of the submarine, d = 185 m
It is at an angle of 15 degrees below the horizontal. We need to find the horizontal component of the submarine's displacement. It is given by :
Substituting the values in above equation as :
So, the horizontal component of the submarine’s displacement is 178.69 meters. Hence, this is the required solution.
Answer:
11.4 m
Explanation:
We are given that
Total distance traveled by cab,d=214 m
Maximum speed of cab=v=315 m/min=
1 min =60 s
Acceleration of cab=
We have to find the distance traveled by the cab while accelerating to full speed from rest.
Initial speed o f cab=u=0
Substitute the values in the formula
Hence, the cab travel 11.4 m from rest to full speed.
There is nothing to choose from
Answer:
It will keep moving at the same speed.
Explanation:
In space, there is vacuum which means that there is no air resistance. Since we remain in the state of free fall in the space, the impact of gravity is also negated on the friction. So the friction will be zero.
As per Newton's first law, we will need to apply external force to change the state of motion of a body. In this case when he let go of the lunch box it has a certain speed. This speed will not changes as there is no friction and no acceleration. So the box will keep on moving with the same speed.
