Question

Jason while driving on Kukum highway at 70 m.s – 1 seeing the traffic light turn red, he applies the brake and comes to rest in a time of 2 seconds. What is his deceleration?

Answer 1

35 m/s^2

Step-by-step explanation:

Decceleration = change in velocity / change in time

= ( 70 m/s ) / 2 seconds = 35 m/s^2

DEcceleration = 35 m/s^2

Jason's speed changes by - 35 m/s^2
