Answer:
5 meters per second squared
Explanation:
We calculate the acceleration using the formula:
a = (vf - vi) / t
where "vf" is the final velocity, "vi" the initial velocity, and "t" the time it took to change from the initial velocity to the final one.
In our case:
a = (45 - 5) / 8 = 40 / 8 = 5 m/s^2
Answer:
Which of the following correctly describes a solid? Explanation: A solid is defined as having a definite shape and definite volume. A liquid is defined as having a definite volume, but not a definite shape.
Answer:
0.90291 m/s
0.45055 m/s
Explanation:
= Mass of canon = 2090 kg
= Mass of ball = 16.7 kg
= Velocity of canon
= Velocity of ball = 113 m/s
In this system the momentum is conserved

The velocity of the cannon is 0.90291 m/s
Applying energy conservation

The ball would travel 113.45055-113 = 0.45055 m/s faster
