A cat falls from a table of height 1.3 m. What is the impact speed of the cat?

To find the impact speed for an object that falls from rest, use the formula:

Vf = sqrt (2gh)

vf is the final velocity/impact speed

g is acceleration due to gravity (9.81m/s^2)

h is the height in metres

so sub the height into the formula and solve for Vf : - )
