Free Fall

A free falling objects under the influence of

• force of air

• force of gravity

• force of resistance

• force of velocity

Free-falling objects do not encounter

• air resistance

• force of gravity

• downward acceleration

• 5m

• 25m

• 50m/s

• 125m

Kenyatta drops on object and it free fall for 5.00 seconds and has a final velocity of 49.0 m/s

• 122.5m

• 250m

• 24.5m

• 0m

A free falling object falls for 1.6s, What is the final velocity?

• -15.68m/s

• -9.8m/s

• -6.125m/s

• -25.088m/s

A ball is thrown downward from the top of a roof with a speed of 25 m/s. After 2s, its velocity will be( down is considered a negative direction):

• 19.6m/s

• -5.4m/s

• -44.6m/s

• 44.6m/s

AN object free fall for 3.5 seconds. How far does it fall?

• 120.05m

• 17.15m

• 60.03 m

• 34.3m

A ball is thrown up in the air with an initial velocity of 40m/s. What is the ball's velocity after 2 seconds?

• 40m/s traveling upward

• 20 m/s traveling upward

• 20 m/s traveling downward

• 40m/s traveling downward

A ball is thrown up in the air with an initial velocity of 40m/s. What is the ball's velocity after 6 seconds?

• 10m/s traveling upward

• 20 m/s traveling upward

• 20 m/s traveling downward

• 10 m/s traveling downward

What values are always known for a free falling object?

• Vi =0m/s

  a= -9.8m/s/s

• Vi = -9.8m/s

  a = -9.8m/s/s

• Vi= -9.8m/s

  a = -9.8m/s/s

• d = -9.8m

  Vi = 0m/s
