# M1 question watch

1. We haven't actually been taught any of mechanics yet so there is a reason I don't know how to do this but we have been given the textbook and when I flicked through the textbook, this first question really confused me. Out of curiosity, how do you do this with only 1 value?

You know 3 values
Starting velocity = 0 (it starts from rest)
Acceleration = 9.8 m/s^2 (Gravity)
Displacement = 40 m

Your text book will explain the kinematics formulae you can then use (SUVAT)

3. you can use a SUVAT equation ?

You actually know 3 values, the 40, "rest" means the iitial velocity was zero, and the acceleration due to gravity is 9.8 ms^(-2) downwards.

Now all you need to know is some formulae.

gdunne wins the race. I'll go back to watching the vuelta
