Explanation:
Given that,
Mass of car = 64 kg
Suppose, a 1400-kg car that stops from 34 km/h on a distance of 1.7 cm.
We need to calculate the acceleration
Using formula of acceleration

Where, v = final velocity
u = initial velocity
a = acceleration
s = distance
Put the value into the formula



We need to calculate the force
Using formula of force



Negative sign shows the direction of the force is in the direction opposite to the initial velocity.
Hence, The force is
