Answer:
0.70046 m/s²
2.732862 N
Explanation:
g = Acceleration due to gravity = 9.81 m/s²
m = Mass of yo-yo = 0.3 kg
R = Radius of rolling disk = 5.1 cm
r = Radius of rod = 1 cm
For a rolling disks the acceleration is given by
The acceleration of the yo-yo is 0.70046 m/s²
The tension in the string will be
The tension in the string is 2.732862 N
Answer:
The acceleration of the train is 5 m/s².
Explanation:
Acceleration is the change in velocity over a given time interval.
Therefore, acceleration is given as:
Where, are initial and final velocities and
is the time interval.
Here,
This gives,
Therefore, the acceleration of the train is 5 m/s².
Alpha decay is your answer. This picture should explain it to some degree.
