A cow is walking at a velocity of 4 m/s and speeds up to 6 m/s in 5 seconds. Calculate the acceleration of the cow. Round your answer to 2 decimal places

0.4 m/s²

Explanation:

average acceleration = (final velocity - initial velocity)/ time elapsed

average acceleration = (6 - 4)/5

average acceleration = 2/5

average acceleration = 0.4 meters/seconds squared or 0.4m/s²

answer is c

explanation:

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
