A car is pushed with a force of 450 N for 19.4 seconds. What impulse was applied to the car?
1 answer:
Answer:
impulse = 8820 kg· or 8820 N·s
Explanation:
Impulse J is equal to the average force multiplied by the elapsed time Δt or in equation form, J =
Δt
As long as your force of 450 N is constant then that value is your average force and your elapsed time is 19.4 seconds.
Multiply these values.
You will get an impulse of 8820 kg· or 8820 N·s.

Answer:
F - fr = ma , N - W = 0
Explanation:
In this exercise we are asked to identify the forces that act on the jack, for this we will use Newton's second law
On the x axis
We have two forces: the friction and the force of the girl who pulls the cat
F - fr = ma
On the y axis
There are two forces: normal and weight
N - W = 0
A diagram of these forces can be seen in the attachment
Answer:
Explanation:
= Tension force in string A = 403 N
= Tension force in string B = 800 N
= diameter of string A = 0.513 mm
= diameter of string B = 1.29 mm
= wave speed of string A
= wave speed of string B
Ratio of the wave speeds is given as
Answer:
Explanation:
By conservation of energy, the sum of the kinetic and gravitational potential energies at the surface of the Earth must be equal than their sum at infinity, so we have:
Where is the gravitational constant,
and
are the mass and radius of the Earth, <em>m </em>is the mass of the particle,
its velocity at the surface of the Earth (which would be its escape velocity) and
and
are the velocities and distance at infinity, which would be null and infinity respectively, so the right hand side of our equation is 0J, which leaves us with:
Also, since the force the molecule experiments is the force of gravity (disregarding drag), we can write its weight in terms of Newton's Law of Gravitation:
Which means that:
So finally putting all together we can write:
