Answer 2

Given:

The velocity of a moving object changes from 10 m/s to 50 m/s in 10 s.

Solution:

• Initial velocity = u = 10 m/s
• Final velocity = v = 50 m/s.

Change in velocity = ∆v = 50-10 = 40 m/s.

• Let Acceleration be 'a':

$a = \dfrac{v - u}{t}$

$\implies \: a = \dfrac{50 - 10}{10}$

$\implies \: a = \dfrac{40}{10}$

$\implies \: a = 4 \: m {s}^{ - 2}$

So, acceleration is 4 m/s².
