Question

You throw a 2 kg ball upward with an initial speed of 20 m/sec. About 4 seconds later, the ball returns and you catch it.
Next, you throw a 4 kg ball up with the same initial velocity and from the same location as the 2 kg ball. How does the time in the air for the two objects compare?
The 4 kg ball is in the air twice as long

The 4 kg ball is in the air four times as long

The 4 kg ball is in the air half as long

The 4 kg ball is in the air for the same amount of time

Answer 1

The 4 kg ball is in the air for the same amount of time if we ignore if friction because the same acceleration due to gravity affects the motion of all bodies on our planet.
