Answer:
Explanation:
The centripetal acceleration of an object in circular motion is the acceleration with which the object is attracted towards the center of the circular orbit. Mathematically, it is given by
where
v is the speed of the object
r is the radius of the orbit
The speed of the object is also given by the ratio between the circumference of the orbit and the orbital period, T:
Substituting into the previous equation, we find a new expression for the centripetal acceleration:
In this problem:
- The radius of the orbit of the Moon is
- The period of the orbit is
Therefore, the centripetal acceleration is:
Answer:
180^2 + 390^2 = force ^2 (Pythagoras) root of force^2 = 429.5N approx resultant force Acceleration = Force/Mass 429.5/270 = 1.5907 ms^-2 in a Southwesterly direction.
Explanation:
Hello!
Begin by finding the acceleration of the puck. Use the kinematic equation:
The initial velocity is 0 m/s since the object was at rest, so we can rewrite the equation as:
Plug in the given distance and time:
Find the net force using the formula F = m · a (Newton's Second Law)
F = 0.18 · 0.1
F = 0.018 N
Answer: The acceleration will be greater in the kickball than the soccer ball since the kick ball has a smaller mass and provided they are acted upon with equal force magnitude.
Explanation:
We can prove this by substituting with numerical values.
Say the force she kicked both balls with was 30 N. The mass of the soccer ball is 10kg and the mass of the kickball is 6kg.
Applying Newtons Second Law, F = ma
For the soccer ball:
30 = 10a
a = 30/10
a = 3
For the kickball:
30 = 6a
a = 30/6
a = 5
Hence the kickball will travel with a greater acceleration given the same force is acted upon and has a smaller mass than the soccer ball
Hope this helps, brainliest would be appreciated :)
