W put this into practice

An athlete accelerates from rest at a constant rate of
0.8 m/s2 for 4s. Calculate the final speed of the athlete.

Answer 1

To find the final speed of the athlete, use the formula Final speed = Initial speed + (Acceleration x Time). Substitute given values and solve for final speed. The final speed of the athlete is 3.2 m/s.

Step-by-step explanation:

Answer:

To solve for the final speed of the athlete, we need to use the formula:

Final speed = Initial speed + (Acceleration x Time)

Given that the athlete starts from rest (initial speed = 0), the acceleration is 0.8 m/s2, and the time is 4 seconds, we can substitute these values into the formula:

Final speed = 0 + (0.8 x 4)

Calculating:

Final speed = 0 + 3.2 = 3.2 m/s

Therefore, the final speed of the athlete is 3.2 m/s.
