An apple falls from a tree and 0.5 seconds later hits the ground.

a. How fast was the apple going just before it hit the ground? Show your work or estimate if you approximate the acceleration due to gravity.

b. How far would the apple have fallen during the 0.5 seconds? Show your work or estimate if you approximate the acceleration due to gravity.

Answer:

Final velocity = 4.9 m/s

h = 1.225 m

Explanation:

Given:

Time taken t = 0.5 sec

Acceleration g = 9.8 m/s²

Computation:

v = u + gt

v = 0 + (9.8)(0.5)

v = 4.9 m

Final velocity = 4.9 m/s

h = 1/2[g][t]²

h = 1/2[9.8][0.5]²

h = 1.225 m
