Uniform acceleration calculation

Question 1

What is the equation of uniform accelration?

Answer 1

(final speed)2 = (initial speed)2 + 2 × acceleration × distance moved

v2 = u2 + 2as

s = distance moved in metres (m)
u = initial speed in metres per second (m/s)
v = final speed in metres per second (m/s)
a = acceleration in metres per second squared (m/s2)

Question 2

What is accelration due to gravetity?

Answer 2

10m/s^2

Question 3

Rearange the formula to fine inital speed?

Answer 3

u^2 = √v^2 - 2as
