Answer:

D. The truck and trailer will experience a net force of 40 newtons backward

Explanation:

Taking the greatest force (trailer), and subtracting it by the smaller force (truck), we can find how many newtons the greater force is applying to pull the whole system:

2,790 - 2,750 = 40 N

Since we know that the trailer is the greater force, the truck & trailer are being pulled backwards by 40 Newtons

1) they are attracting because if you look at the arrows they’re all pointing the same way.

2) if the magnet was turned around they would do the opposite and not attract ( this is called repulsion)

3) magnetic pole

4)magnet

5) magnetic force

6) magnetism

Hope this helps

What is the acceleration of a car initially traveling at -5m/s and<br> reaching -22m/s in 3s.
lozanna [386]

Answer:

a=-5.67\ m/s^2

Explanation:

Given that,

Initial velocity, u = -5 m/s

Final velocity, v = -22 m/s

Time, t = 3s

We need to find the acceleration of the car. The formula of it is given by :

Acceleration,

a=\dfrac{v-u}{t}\\\\a=\dfrac{(-22)-(-5)}{3}\\\\a=-5.67\ m/s^2

So, the acceleration of the car is -5.67\ m/s^2.
