Physics: Ball thrown from a building

What is the initial velocity of the ball thrown downward from the roof of the building?

• 5 m/s

• 10 m/s

• 15 m/s

• 0 m/s

What is the height of the building from which the ball is thrown?

• The height of the building can be calculated using the kinematic equation for free fall.

• The height of the building is inversely proportional to the ball's speed

• The height of the building is determined by the color of the ball

• The height of the building is irrelevant to the ball's trajectory

Which kinematic equation can be used to solve this problem?

• v_f = v_i + at

• v_f = v_i / t

• v_f = v_i * t

• v_f = v_i^2 + 2as

What is the acceleration of the ball during free fall?

• 8.33 m/s^2

• 5.67 m/s^2

• 9.81 m/s^2

• 10.25 m/s^2

Explain the concept of free fall and its impact on the motion of the ball.

• In free fall, the ball's velocity decreases as it falls.

• Free fall is when an object moves upwards due to gravity.

• Free fall is the motion of an object solely under the influence of gravity, resulting in acceleration downwards at a constant rate of 9.81 m/s^2. The ball's velocity increases, and its potential energy decreases as it falls.

• The motion of the ball in free fall is not affected by gravity.
