To find the final speed after 5 seconds, we can use the following equation:
Vf = Vi + at
Vf = 40 m/s + (-5 m/s^2)(5 s)
Vf = 40 m/s - 25 m/s
Vf = 15 m/s
Therefore, the final speed of the body after 5 seconds will be 15 m/s.
1.If a body is moving at an acceleration of -5 m/s2. If the initial speed was 40m/s, what will be the speed in 5 seconds?
