Using the equation v = u + gt, we can substitute the values: v = 0 + 9.8 x 2 v = 19.6 m/s
An object is dropped from a height of 100 m. What is its velocity just before it hits the ground? Freefall Mathematics Velocity Book 4 Answers
where: v = final velocity u = initial velocity (which is usually 0) g = acceleration due to gravity (approximately 9.8 m/s^2) t = time Using the equation v = u + gt,
