Explanation:
Or a switch
How long it takes to revolve around the sun
Answer:
a.
b.
Explanation:
Given:
Mass of the baseball =
The initial velocity of the baseball = 20m/s
The force acting on the baseball is only due to gravity and the air resistance is negligible. The baseball acceleration is constant due to gravity.
According to Newton's second law:
----------(1)
where mass of the baseball
Put all the value in equation 1.
Therefore, the force on the ball when it reaches half of its maximum height is .
Similarly, the force acting on the ball when its peak .
The answer is; The cloud is cool and lies between you and a hot star.
