Answer:
The force needed to launch the projectile is 150000 N.
Explanation:
We can find the force using the following equation:
Where:
m: is the mass = 15 kg
a: is the acceleration
First, we need to find the acceleration of the projectile:
Where:
: is the final speed
: is the initial speed = 0
x: is the distance = 2 m
The final speed is:
Then, the acceleration is:
Finally, the force is:
Therefore, the force needed to launch the projectile is 150000 N.
I hope it helps you!
Because it reverses an image there for making the objects appear on opposite side
Option D is the correct answer. Option C is incorrect cuz temperature is not constant in outer space which makes difficult for classification. So composition of objects matters. Hence D. Hope it helps.
