Answer:
The darts hit the same general area of the board.
Answer:
zero
Explanation:
For the box remaining at rest, the total acceleration on the box must be zero. Since force F = m*a, the force F must also be zero.
(500 m) / (580 m/s) = 0.862 second
(8,750 m) / (580 m/s) = 15.09 seconds
Answer:
An attraction between two objects that have mass :)
Answer:
kE=0.0735 J
Explanation:
Given that
Radius ,R=10 cm = 0.1 m
Mass ,m= 3 kg
Angular speed ,ω = 3.5 rad/s
We know that moment of inertia for solid sphere given as

Kinetic energy

Now by putting the values


kE=0.0735 J
Therefore the kinetic energy will be 0.0735 J
