Calculate the acceleration of a ball has been dropped from the roof. It accelerates from 10 m/s to 30 m/s in 2 sec. 1 point 15 m
Andre45 [30]

Answer:

10 m/s/s or m/s²

Explanation:

Acceleration can be calculated by using the formula;

a = v - u/t

Where;

a = acceleration (m/s²)

v = final velocity (m/s)

u = initial velocity (m/s)

t = time (s)

In other terms, acceleration (a) can be represented as ∆V/t.

According to this question, a ball accelerates from 10 m/s (u) to 30 m/s (v) in 2 seconds. Hence, the acceleration of the ball is as follows:

a = 30 - 10/2

a = 20/2

a = 10m/s².
