option (e) is correct.
the acceleration due to gravity always acts downwards with same magnitude on all three balls.

do comment in case any doubt, will reply for sure . Goodluck
Ball A is dropped from rest from a window. At the same instant, ball B is...
At the same instant that a 9.2 kg ball is dropped from 219 m above the Earth's surface, a second ball, with a mass of 16.2 kg, is thrown straight upward from the Earth's surface with initial velocity of 13.4. They move along nearby vertical paths and pass without colliding. Calculate the velocity of the center of mass of the two ball system after 11.0 s. A negative answer is okay, can you interpret that physically? NOTE: Be sure to...
At the same instant that a 9.9 kg ball is dropped from 76 m above the Earth's surface, a second ball, with a mass of 15.0 kg, is thrown straight upward from the Earth's surface with initial velocity of 8.86 They move along nearby vertical paths and pass without colliding. Calculate the position relative to the surface of the Earth of the center of mass of the two-ball system after 6.57 s. A negative answer is okay, can you interpret...
2. A ball is dropped from the top of a 20 m building at the same time that another ball is thrown upward from a height of 2 m above the ground. If the two balls pass on an other at the height of 10 m, determine the speed at which the second ball was thrown upward Answer | 12.6 m/s.
A ball is thrown upward from the ground with an initial speed of 16.6 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height above the ground?
At the same instant that a 9.44 kg ball is dropped from 105 m above the Earth's surface, a second ball, with a mass of 14.4 kg, is thrown straight upward from the Earth's surface with initial velocity of 9.8 . They move along nearby vertical paths and pass without colliding. Calculate the position relative to the surface of the Earth of the center of mass of the two-ball system after 3.79 s. A negative answer is okay, can you...
A ball is thrown upward from the ground with an initial speed of 20.0 m/s; at the same instant, another ball is dropped from a building 12 m high. After how long will the balls be at the same height?
A ball is thrown upward from the ground with an initial speed of 20.2 m/s; at the same instant, another ball is dropped from a building 20 m high. After how long will the balls be at the same height?
At the same instant that a 9.57 kg ball is dropped from 41 m above the Earth's surface, a second ball, with a mass of 21.5 kg, is thrown straight upward from the Earth's surface with initial velocity of 3.22 m. They move along nearby vertical paths and pass without colliding. Calculate the position relative to the surface of the Earth of the center of mass of the two-ball system after 4.62 s. A negative answer is okay; can you...
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2. What is the speed of the...
A red ball is thrown down with an initial speed of 1.2 m/s from a height of 25 meters above the ground. Then, 0.6 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 0.8 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. 1)What is the speed of the...
