Work done = force * distance
work done = 200 * 20
work done = 4000J
Answer:
Height, H = 25.04 meters
Explanation:
Initially the ball is at rest, u = 0
Time taken to fall to the ground, t = 2.261 s
Let H is the height from which the ball is released. It can be calculated using the second equation of motion as :

Here, a = g
H = 25.04 meters
So, the ball is released form a height of 25.04 meters. Hence, this is the required solution.
2,450 miles. you have to do 700•3.5= 2,450
Answer:within the focal length of the lens, provided the focal length is shorter than the near point distance.
