A freely falling object starts from rest. After falling for 6 seconds, it will have a speed of about:

• 6 ms^-1

• 30 ms^-1

• 60 ms^-1

• 300 ms^-1

When can you not use the suvat equations?

• For a falling object.

• When acceleration is constant.

• When velocity is changing by a constant amount.

• When acceleration is changing.
