"The diurnal motion" of the stars is defined as the apparent daily motion of stars around the Earth. The cause for this "apparent motion of stars" was proposed by Heraclides (who was a Greek philosopher and astronomer). He afirmed that this was created by the Earth's rotation on its axis, which is completed in 23 hours, 56 minutes and 4.09 seconds.
Answer:
v = 14.41 m/s
Explanation:
It is given that,
mass of the ball, m = 200 g = 0.2 kg
Height of the roof, h = 12 m
The ball is tossed 1.4 m above the ground, h' = 1.4 m
Let v is the minimum speed with which the ball is tossed. Using the conservation of energy to find it as :





v = 14.41 m/s
So, the minimum speed with which the ball is thrown straight up is 14.41 m/s. Hence, this is the required solution.
