Equation for acceleration

Answer 1

acceleration(a) = (final velocity(v) - Initial velocity(u)) / time (s)

Algebraically

a = (v - u) / t

Where 'v' & 'u' are measured in metres per second ( m/s) or ms^-1

And 't' is the time in seconds measured is 's'

Hence

a(ms^-2) = v(m/s) - u(m/s)) / t(s)

And example is a car starting from rest up to 44 m/s ( 30 mph) in 10 seconds.

a = (44 - 0 ) / 10

a = 44/10

a = 4.4 ms^-2.

NB Earth's gravitational acceleration(g) is approximately 10 ms^-2.

Answer 2

(Final Velocity - Initial Velocity) / Time
