Question

a particle with a velocity of 2m/s at t=0 moves along a straight line with a constant acceleration of o.2m is 2. find the displacement of the particle in 10s

Answer 1

Answer:

30m

Explanation:

Given => Velocity of the particle = u =2m/s  

          =>Time taken by the particle t = 10s

          =>Constant acceleration = a = 0.2m/s²  

Using the second equation of motion -  

S = ut + 1/2at²

= 2 × 10 + 0.5 × 0.2 × 10 × 10

= 20+10

= 30m

Answer 2

Cᴏʀʀᴇᴄᴛ Qᴜᴇsᴛɪᴏɴ :

➥ A particle with a velocity of 2 m/s at t = 10 moves along a straight line with a constant acceleration of 0.2 m/s² m is 2. Find the displacement of the particle in 10s

Aɴsᴡᴇʀ :

➥ Displacement of particle = 30 m

Gɪᴠᴇɴ :

➤ Velocity (v) = 2 m/s

➤ Time (t) = 10 sec

➤ Acceleration (a) = 0.2 m/s²

Tᴏ Fɪɴᴅ :

➤ Displacement of particle (s) = ?

Sᴏʟᴜᴛɪᴏɴ :

⤵ From second equation of motion.

$\sf{: \implies s = ut + \dfrac{1}{2} a {t}^{2} }$

$\sf{: \implies s = 2 \times 10 + \dfrac{1}{2} \times 0.2 \times {10}^{2} }$

$\sf{: \implies s = 20 + 10}$

$: \implies \underline{ \overline{ \boxed{ \purple{ \bf{ \: \: s = 30 \: m \: \: }}}}}$

Hence, the displacement of particle is 30m.
