Question

A body start from rest and reaches to 10 m/s speed in 5 seconds, then what is its acceleration?​

Answer 1

Answer:

u = 0m/s ( initial velocity )

v = 10 m/s ( final velocity )

t = 5 seconds

a = v-u/t

a = 10-5/5

a = 5/5 = 1m/s²

Answer 2

• initial velocity=u = 0 m/s
• final velocity=v = 10 m/s
• time=t = 5 s

${\boxed{\sf Acceleration=\dfrac{Final\;velocity-Initial\;velocity}{Time}}}$

$\sf\longrightarrow A=\dfrac{10-0}{5}$

$\sf\longrightarrow A = \dfrac{10}{5}$

$\sf\longrightarrow A = 2\;m/s^2$

Its acceleration is 2 m/s^2
