From the momentum conservation we know that the initial momentum is equal to the final momentum. The momentum in a singular way can be defined as the product between the mass and the velocity of an object. In the presented system, however, there are two objects, therefore the mass of both and the speed of both, before and after the collision must be taken into account. Mathematically we could describe this as
Here,
= Mass of each object
= Initial velocity of each object
= Final velocity of each object
From here we can realize that it is necessary to use the system on both cars to be able to predict what will happen either with their masses, or their speeds.
The correct answer is C.
Answer:
We have that Assuming No air resistance,the initial horizontal velocity of the cannonball is
From the question we are told that
A cannonball is shot from a cannon at a launch angle of 35 and an initial velocity of 147 m/s
Generally the equation for the horizontal velocity is mathematically given as
Therefore
Therefore Assuming No air resistance,the initial horizontal velocity of the cannonball is For more information on this visit
Explanation:
The answer for this question is, it was attempting to make the motor cycle safe
The amount of C-14 at time t is
where
N₀ = inital amount of C-14
t = years
K = 0.0001 = 10⁻⁴
When the skull was discovered, the amount of C-14 contained 43% of N₀.
Therefore
Answer:
The age of the skull s 8440 years (nearest integer)
