Falling for 1 second it would have accelerated to 9.8 metres per second
so the answer is 9.8*0.05=0.49m/sec
that is your answer
When an object moves its length contracts in the direction of motion. The faster it moves the shorter it gets in the direction of motion.
The object in this question moves and then stops moving. So it's length first contracts and then expands to its original length when the motion stops.
The speed doesn't have to be anywhere near the speed of light. When the object moves its length contracts no matter how fast or slow it's moving.
It’s the velocity to the trex then divided by pie to get 8.3
Answer:
Explanation:
given,
radius of circle = 1.8 m
mass of the ball = 0.1 Kg
linear speed of the ball = 27 m/s
angular velocity of orbit = ?
ω is the angular speed of the circle
the angular velocity of the orbit is
A is incorrect. B is totally incorrect. And so is D. I think
