Answer:
Explanation:
Given
Horizontal bar rises with 300 mm/s
Let us take the horizontal component of P be
where 
is angle made by horizontal bar with x axis
Velocity at y=150 mm
thus 
position of
Velocity at this instant
Considering the definition of impulse, the impulse of the force is 11.06 N×s.
<h3>Impulse</h3>
Impulse is a term that quantifies the overall effect of a force acting over time.
In other words, the mechanical impulse of a force relates said force to the duration of its action. It is a vectorial magnitude that has the direction and sense of the force that produces it.
The impulse I is the product between a force and the time during which it is applied:
I= force× time
The unit of the impulse is the N×s (newton per second).
<h3>This case</h3>
In this case, you know:
- Force= 1400 N
- Time= 0.0079 seconds
Replacing in the definition of impulse:
I= 1400 N× 0.0079 s
Solving:
<u><em>I= 11.06 N×s</em></u>
The impulse of the force is 11.06 N×s.

Only your weight would change. Mass is a measurement of how much matter something is made up of.
It's quite easy to get the answer. Think about it: liters and mililiters both are measure of volume - withdraw, <span> grams are used to measure mass.
The one remained is </span>C. fermi(<span> femtometer)</span> which is obviously correct answer.
Answer:
a = 64 ft / s²
Explanation:
The force in a spring is given by Hooke's law
F = -k x
Let's use the initial data to calculate the spring constant
k = F / x
Reduscate to the English system
x = 3 in (1foot/12 in) =0.25 foot
k = 0.3 / 0.25
k = 1.2 lb / foot
Now we can use Newton's second law
F = ma
a = F / m
a = -k x / m
m = w / g
m = 0.3 / 32 = 0.009375
x= 6 in (1foot /12 in)= 0.5 foot
a = - 1.2 0.5 / 0.009375
a = 64 ft / s²
