Homework Statement
A 0.5 kg tennis ball is dropped from rest at a height of 5.6 m onto a hard floor.
Homework Equations
a) What is the speed of the ball at the instant of contact with the floor?
v = m/s
The Attempt at a Solution
I need acceleration and I have attempted using the equation:
v^2 = u^2 +2as to solve for a. I set the variables as follows:
v = 0
u = 9.81
s = 5.6
I got a = 8.6 as my answer.
I either have the wrong equation or I am making a mistake on how I set it up.
I know this is a one-dimension kinematic problem but I have been having trouble setting these up, any help in the right direction is much appreciated!
