Question

the brakes applied to a car produce a negative acceleration of 10 m per second if the car takes 5 seconds to stop before applying brakes calculate the distance covered by the car before coming to rest​

Answer 1

Answer:

Here final velocity v=0, hence the total distance travelled will be S = - 1 2 a t 2 . Here a=-10 m/s2 and time t=5 s.. So the distance travelled is S = - 1 2 × - 10× 5 2 = 125 m. ... The Questions and Answers of The brakes applied to a car produces a negative acceleration of 10m/s^2.
