2 points

Option 1

+ 2 m/s2

− 2 m/s2

− 0.5 m/s2

+0.5 m/s2
​

Answer 1

Answer:

+0.5 m/s2

Explanation:

When a car driver travelling at a speed of 10 m/s applies brakes and brings the car to rest in 20 s, then retardation will be : Options. + 2 m/s2. − 2 m/s2. − 0.5 m/s2. + 0.5 m/s2. Solution Show Solution. + 0.5 m/s2. The term “retardation” means negative acceleration. Initial velocity = 10 m/s. Final velocity = 0 m/s.
