Answer:
a = 1.16 m/s²
Explanation:
In order to find the acceleration of the ball we will use 3rd equation of motion.
2as = Vf² - Vi²
where,
a = acceleration = ?
s = displacement = 21.9 m
Vf = Final Velocity = 7.14 m/s
Vi = Initial Velocity = 0 m/s (Since, ball starts from rest)
Therefore, using the values, we get:
2a(21.9 m) = (7.14 m/s)² - (0 m/s)²
a = (50.97 m²/s²)/(43.8 m)
<u>a = 1.16 m/s²</u>
Answer:
Magnitude of fourth displacement is approximately 95 metres,
Direction of fourth displacement is straight west.
The answer is A. 1000 times smaller
The metric prefix mili- is used to signify something 1000 times smaller than a measure. For example in 1 meter there are 1000 milimeters. Therefore; A is correct.
Hope this helped. Have a great night!
Answer:
A)
B)
Explanation:
A)
= magnitude of charge on each sphere =
= Distance between the two spheres = 10 cm = 0.10 m
= magnitude of force between the two spheres
Using Coulomb's law, magnitude of the force between two charged sphere
B)
= mass of the sphere =
= Force of gravity in down direction =
= Electrostatic force of repulsion in upward direction =
= acceleration of the sphere
Force equation for the motion of the sphere is given as
