Question

An apple dropped from the branch of a tree hits the ground in 0.5 s. If the acceleration of the apple during its motion is 10 ms-2 in the downward direction. Calculate ----- Its speed just before it hits the ground. What is its average velocity during 0.5 s? Calculate the height of the branch of the tree from the ground?

Answer 1

Answer:

h=1/2gt^2

=5x0.25

=1.25 m

v=√2gh

=√20x1.25

=√125x2/10

=√25

=5 m/ s

Answer 2

5 m/s
