Answer:2t
Explanation:
Given
Jason throwing watermelon at speed v and it spend t time in air
time to reach max height
0=v-gt'
and time to reach bottom is also t'
t=2t'
For guy throws his watermelon at speed 2v
So total time in air will be
t''=2t
The tangential speed of an orbiting object is
Explanation:
The tangential speed of an orbiting object is defined as the ratio between the distance covered in one revolution and the period of revolution:
where
d is the distance covered during one period
T is the orbital period
However, the distance covered during one period is the circumference of the circle:
where
r is the radius of the circle
Substituting the 2nd equation into the 1st equation, we find:
So, this is the final expression for the tangential speed of an orbiting object.
