What is the mass of a cannonball if a force of 2,500 N gives the cannonball an acceleration of 200 m/s2? Question 5 options: 15.
1 answer:
The mass of the given cannonball is 12.5 kg. Option B is correct.
<h3>What is Acceleration?</h3>
It is defined as the change in the direction and speed of the object. It is a vector quantity.
From, Newton's second law of motion
Where,
- force = 2,500 N
- mass
- acceleration = 200 m/s²
Put the values in the formula,
Therefore, the mass of the given cannonball is 12.5 kg.

Answer:
-1.43 m/s relative to the shore
Explanation:
Total momentum must be conserved before and after the run. Since they were both stationary before, their total speed, and momentum, is 0, so is the total momentum after the run off:
where are the mass of the swimmer and raft, respectively.
are the velocities of the swimmer and the raft after the run, respectively. We can solve for
So the recoil velocity that the raft would have is -1.43 m/s after the swimmer runs off, relative to the shore
Answer:
43.7 °C
Explanation:
= Coefficient of linear expansion of brass =
= Coefficient of linear expansion of steel =
= Initial length of brass = 31 cm
= Initial length of steel = 11 m
= Total change in length = 3 mm
Total change in length would be
The final temperature is 43.7 °C
