## Deceleration Force Formula:

Deceleration force is the force exerted on an object to decrease its velocity over a certain period.

Deceleration force, DF(N) in Newtons is equal to product of difference of initial velocity, Vi(m/s) in metre per second and final velocity, Vf(m/s) in metre per second and mass, m(kg) in kilograms and dividing by time, t(s) in seconds.

Deceleration force, DF(N) = ((Vi(m/s) – Vf(m/s)) / t(s)) * m(kg)

DF(N) = deceleration force in Newtons, N.

Vi(m/s) = initial velocity in metre per second, m/s.

Vf(m/s) = final velocity in metre per second, m/s.

t(s) = time in seconds, s.

m(kg) = mass in kilograms, kg.

### Deceleration Force Calculation:

1. A car with a mass of 1200 kg decelerates from 25 m/s to 0 m/s in 8 seconds. Calculate the deceleration force applied to the car.

Given: Vi(m/s) = 25m/s, Vf(m/s) = 0m/s, t(s) = 8s, m(kg) = 1200kg.

Deceleration force, DF(N) = ((Vi(m/s) – Vf(m/s)) / t(s)) * m(kg)

DF(N) = ((25 – 0 ) / 8) * 1200

DF(N) = (25 / 8 ) * 1200

DF(N) = 3750N.

1. A vehicle applies a deceleration force of 3000 Newtons to come to a stop from a speed of 30 m/s to 0 m/s in 5 seconds. Calculate the mass of the vehicle.

Given: Vi(m/s) = 30m/s, Vf(m/s) = 0m/s, t(s) = 5s, DF(N) = 3000N.

Deceleration force, DF(N) = ((Vi(m/s) – Vf(m/s)) / t(s)) * m(kg)

m(kg) = DF(N) * t(s) / (Vi(m/s) – Vf(m/s))

m(kg) = 3000 * 5 / (30 – 0)

m(kg) = 500kg.
