Answer:
<h3>The answer is option A</h3>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the Force
m is the mass
From the question we have
We have the final answer as
<h3>0.617 m/s²</h3>
Hope this helps you
Answer: 45000 m/s^2
Explanation:
First, we know:
Bullet's Initial Velocity (Vo) = 0 m/s
Distance Travelled (D) = 1 m
Final Velocity (Vf) = 300 m/s
We need to know the bullets acceleration to reach the final velocity on that distance. Because the bullet stars from rest, his Initial Velocity is equal to zero.
We dont know on how much time it takes for the bullet, but we know the acceleration on the barrel is constant.
We can use the following equation for this
Because Vo is zero, the equation simplify, so we have.
Searching for the accelaration we obtain
Changing values
This is the acceleration needed to reach the velocity at the end of the barrel.
"Decimeter" is a unit of length or distance, whereas "milliliter" is
a unit of volume. They measure different quantities, and have
different physical dimensions. Neither one can be converted to
the other one.
If it were possible to convert volume to length or distance, you
(or someone with a better handle on his math and physics) could
figure out how many inches of milk you poured on your cereal.
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
