How do you solve for decceleration?

Answer 1

Deceleration is where the force is opposite to direction of motion and so the force and therefore acceleration will be negative, say your 10 kg mass (m)

is at 20 m /s (u), apply a 100 n force (f) against the direction of motion,

so a = f / m = -100 / 10 = -10ms^2

Say you want to know the distance (s) to come to rest(v)

a = -10 ms^2

u = 20 m / s

v = 0 m / s

shuffle v^2 = u^2 + (2*a*s) to isolate s:

s = (v^2 - u^2) / (2 * a) = -400 / -20 = 20 metres

Answer 2

To calculate deceleration, subtract the final velocity from the initial velocity and then divide by the time taken for the change in velocity to occur. The formula is: a = (vf - vi) / t, where a is the deceleration, vf is the final velocity, vi is the initial velocity, and t is the time taken. Deceleration is measured in units of acceleration (m/s^2).
