Physics

viva [34]2 years ago
5 0

Answer:

The cars would both move in the direction with the greatest momentum.  We know the truck would have the greatest momentum due to having the greatest mass. Plus, factors which affects momentum are mass and velocity.    

Thus, the car would move forward towards the direction of momentum of the truck. Both will continue to move at the same velocity.

E.g. truck hits the back of a stationary car, both will move forward, to the right & travelling at the same speed, but lower than the initial velocity of the truck. Now the total the total momentum before the collision is the same as the total momentum after the collision; as a result, momentum has been conserved.

Hope this helps!

A 1600kg cannon fires a 5kg cannonball horizontally. The exit velocity of the cannonball is 80m/s and the barrel length is 2m. W
evablogger [386]

Answer:

 a = 1600 m / s²

Explanation:

For this exercise we use the kinematics relations,

         v² = v₀² + 2 a x

where v₀ is the initial velocity of the bullet, which as part of rest is zero, for the distance (x) we can assume that the gases accelerate along the entire trajectory of the cannon x = 2m

         a = \frac{v^2}{2x}

let's calculate

         a = \frac{80^2}{2 \ 2}

         a = 1600 m / s²

Why is it not posible to see the other waves on the electromagnetic spectrum???
Montano1993 [528]
It is not possible to see the other waves on the electromagnetic spectrum because only other species can see the other parts of the spectrum because they have different components in their eyes than we do, therefore, only allowing us to see a
portion of the spectrum, which is visible light.
