(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 0.5 kg tennis ball is dropped from rest at a height of 5.6 m onto a hard floor.

2. Relevant equations

a) What is the speed of the ball at the instant of contact with the floor?

v = m/s

3. 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!
