Question

A car is moving with constant
velocity l0m/s. When brakes are
applied it comes to half in 1.2s
What is the retardation​

Answer 1

Answer:

Retardation is -8.33

Explanation:

Retardation is negative

And acceleration is posetive

intial velocity = 10m/s

and final velocity = 0m/s

retardation = final velocity - intial velocity ÷time

0-10÷1.2=-8.33
