Question

A rock is dropped from a cliff, how far does it drop in 1.4 seconds?
What is the speed of a rock dropped from a cliff after 2.7 seconds?

Answer 1

Answer:

Explanation:

1) either all the way to the ground, or, if the cliff is high enough,

h = ½(9.8)1.4² = 9.6 m

2) If the cliff is high enough and we ignore air resistance

v = 9.8(2.7) = 26 m/s
