Question

A car is travelled at 8m/s. The mass of the car is 750 kg.

Calculate the force required to stop the car in 8s

Answer 1

F = 750N

Step-by-step explanation:

We know that F(force) = mass(m) × acceleration(a)

And that Acceleration(a) = velocity(V) ÷ time(t)

So we'll first calculate the acceleration

a = V = 8m/s = 1m/s²

t 8

Next we'll calculate the force

F = ma = 750kg × 1m/s² = 750N
