Question

Suppose that the equation of motion for a particle (where s is in meters and t in seconds) is

s = 5 t^2 - 8 t + 3
find the acceleration at the instant when the velocity is at 0

Answer 1

Differentiate equation
v = 10t - 8
Differerentiate again
a = 10

Accelleration will always be 10m/s^-2
