Answers - Freefall Mathematics Velocity Book 4

An object is dropped from a height of 50 m. What is its velocity just before it hits the ground?

An object is dropped from rest at a height of 200 m. What is its velocity after 4 seconds? Freefall Mathematics Velocity Book 4 Answers

v = u + gt

where: v = final velocity u = initial velocity (which is usually 0) g = acceleration due to gravity (approximately 9.8 m/s^2) t = time An object is dropped from a height of 50 m

34.6 m/s

Using the equation v = √(2gs), where s is the displacement (50 m), we can substitute the values: v = √(2 x 9.8 x 50) v = √980 v = 31.3 m/s Freefall Mathematics Velocity Book 4 Answers
