Question

When a car driver traveling at a speed of 10 m/s applis brakes and brings the car to rest in 20 s,then retardation will be

Answer 1

u = 10 m/s
v = 0 m/s
t = 20 s
a = (v-u)/t
= -10/20 m/s²
= -0.5 m/s²
so retardation will be 0.5 m/s²

Answer 2

Answer:

Explanation:u = 10 m/s

v = 0 m/s

t = 20 s

a = (v-u)/t

= -10/20 m/s²

= -0.5 m/s²

so retardation will be -0.5 m/s² hope it is helpful for you
