The the magnitude of the average acceleration during the impact is 9.8 m/s² and the time of motion is 1.11 s.
<h3>Average acceleration of the lead weight during the impact</h3>
The lead weight will fall under the influence of gravity with magnitude of 9.8 m/s².
<h3>Time of motion of the lead weight</h3>
t = √2h/g
where;
- h is the total height of fall, h = 6 m + 0.4 cm = 6.004 m
- g is acceleration due to gravity
t = √((2 x 6.004)/9.8)
t = 1.11 s
Thus, the the magnitude of the average acceleration during the impact is 9.8 m/s² and the time of motion is 1.11 s.

Answer:
According to this law, the force exerted between two point charges
i) is directly proportional to the product of their strengths.
ii) is inversely proportional to the square of the distance between them. and
iii) is inversely proportional to the absolute permittivity of the surrounding medium.
This is known as Coulomb's Law.
By definition, we have that the speed is given by:
Where,
d: distance traveled
t: time to travel said distance
Substituting values we have:
Then, rounding the obtained speed we have:
Answer:
Kenneth's average speed is:
v = 4.8 mph
Answer:
c
Explanation:
When a satellite is orbiting the earth , a constant force is being applied on it which means it must has acceleration. Also the direction of satellite is always being changed when it is orbitting to there is always change in the velocity vector which means acceleration.
You can view in the attached diagram to understand how the velocity is being changed.
