Answer:

F = -319.2 N

Step-by-step explanation:

Given that,

The mass of a bicyclist, m = 70 kg

Mass of the bicycle = 9.8 kg

The speed of a bicycle, v = 16 m/s

We need to find the magnitude of the braking force of the bicycle come to rest in 4.0 m.

The braking force is given by :


F=ma\\\\=(m(v-u))/(t)\\\\=((70+9.8)(0-16))/(4)\\\\=-319.2\ N

So, the required force is 319.2 N.
