As per FBD while its accelerating upwards
we can say that
here normal force is given as
now mass is given as
now we will have
Now while accelerating downwards we can say by FBD
again plug in all values
A body moves due north with velocity 40 m/s. A force is applied
1 answer:
Answer:
the direction of rate of change of the momentum is against the motion of the body, that is, downward.
The applied force is also against the direction of motion of the body, downward.
Explanation:
The change in the momentum of a body, if the mass of the body is constant, is given by the following formula:
p: momentum
m: mass
: change in the velocity
The sign of the change in the velocity determines the direction of rate of change. Then you have:
v2: final velocity = 35m/s
v1: initial velocity = 40m/s
Hence, the direction of rate of change of the momentum is against the motion of the body, that is, downward.
The applied force is also against the direction of motion of the body, downward.

Answer:
The west component of the given vector is - 42.548 meters.
Explanation:
We need to translate the sentence into a vectoral expression in rectangular form, which is defined as:
Where:
- Horizontal component of vector distance, measured in meters.
- Vertical component of vector distance, measured in meters.
Let suppose that east and north have positive signs, then we get the following expression:
The west component corresponds to the first component of the ordered pair. That is to say:
The west component of the given vector is - 42.548 meters.
