Question

A 2200kg suv hits a wall and goes from 26 m/s to 0 m/s in 0.2 seconds how much force did the driver experience

Answer 1

Answer:

286,000N or 268KN

Explanation:

When the SUV was on motion it initial velocity becomes 0m/s and final velocity becomes 26m/s.

Now; from the equation of Sir, Newton.

F=ma where a=v-u/t

So from here we can say:

F=m(v-u)/t by substituting a for v-u/t.

Now F=2200(26-0)/0.2

F=57200/0.2

F=286KN or 286,000N

NB: F= force

a= acceleration

m= mass

t= time.
