Answer:
The initial velocity is 38.46 m/s.
Explanation:
The horizontal distance travel by the tennis ball = 13 m
The height at which the tennis ball dropped = 56 cm
Now calculate the initial speed of tennis ball.
The vertical velocity is zero.
Below is the calculation. Here, first convert centimetre into kilometre. So, height at which ball dropped is 0.56 km.




I would say the expandable one
I’m not sure if I’m right, if I am I hope this helped you, have a wonderful day!
Answer:
from the position of the center of the Sun
Explanation:
As we know that mass of Sun and Jupiter is given as


distance between Sun and Jupiter is given as

now let the position of Sun is origin and position of Jupiter is given at the position same as the distance between them
so we will have


from the position of the center of the Sun
Newton #2: F = M a
(1 x 10³ kg) (4.5 m/s²) = 4,500 newtons
The net force is (40 Newtons) (down the road).
But 40 Newtons is not going to move a piano very enthusiastically.
