Question

an object moving to the right has a decrease from 5m/s to 1m/s in 2s. what is this the average acceleration, what does the result means

Answer 1

Answer:

Answer: Average acceleration is given by, a = -2 m/s^2

Explanation:

Let u = initial velocity of object = 5 m/s

Let v = final velocity of object = 1 m/s

Let t = duration of time = 2 s

Let a = average acceleration of object = ?

a = (v - u) / t = (1 m/s - 5 m/s) / 2 s = -2 m/s^2

a = -2 m/s^2 ---------------------------(answer)

This results means that acceleration is negative. The negative acceleration is also called as deceleration.
