It's known as the law of equal areas
<h2>
Answer:</h2>
(d) it is freely falling but it has a high tangential velocity.
<h2>
Explanation:</h2>
The Moon does not crash into the Earth because it is freely falling but it has a high tangential velocity, that is, actually the moon is falling toward the earth, but since it's moving so fast, then it will never hit the earth. The moon is so far away from the earth and move so fast that it falls around the earth in a continuous circular path. In other words, the high tangential velocity makes the moon to move around the earth. If the moon was moving slowly, gravity would make the moon to fall into the earth.
Here, S = ut + 1/2 at²
381 = 0*t + 1/2 * 9.8 * t²
762/9.8 = t²
t = √77.75
t = 8.82 sec
In short, Your Answer would be 8.82 s
Hope this helps!
Answer:
v = 8.96 m/s
Explanation:
Initial speed of the ball, u = 10 m/s
It caught 1 meter above its initial position.
Acceleration due to gravity,
We need to find the final speed of the ball when it is caught. Let is equal to v. To find the value of v, use third equation of motion as :
v = 8.96 m/s
So, the speed of the ball when it is caught is 8.96 m/s. Hence, this is the required solution.
