Question

a car is moving at a speed of 50 M per second driver accelerates the car and increases the speed from 50 m/s 200 m/s in 10 seconds find the acceleration of the car​

Answer 1

Given :

• Initial Velocity (u) = 50 m/s²

• Final Velocity (v) = 200 m/s²

• Time taken (t) = 10 seconds

___________________....

To Find :

• Acceleration of car = ?

___________________....

Answer:

$:\implies \sf Acceleration = \dfrac{Final \: Velocity - Initial \: Velocity}{Time}$

$:\implies \sf Acceleration = \dfrac{200- 50}{10}$

$:\implies \sf Acceleration = \dfrac{150}{10}$

$:\implies \textsf{ \textbf{ {Acceleration = 15 ms ^{ - 2} }}}$

Answer 2

$\huge {\orange {\bf {\underline {\underline {AnSwer}}}:-}}$

The Acceleration of the car is 15m/s²

━━━━━━━━━━━━━━━

Explaination :-

⟶ Gíven :-

• Initial Velocity, u = 50 m/s
• Final Velocity, v = 200 m/s
• Time taken, t = 10 seconds

⟶ To fínd :-

Acceleration of the car

⟶ Solutíon :-

using 1st equation of motion

i.e.,

$\longrightarrow \bf v = u + at$

$\longrightarrow \sf 200 = 50 + a(10) \\ \\ \longrightarrow \sf 200 - 50 = 10a \\ \\ \longrightarrow \sf 150 = 10a \\ \\ \longrightarrow \sf a = \cancel \frac{150}{10} \\ \\ \longrightarrow \boxed{ \bf a = 15 {ms}^{ - 2} }$

Thus, the acceleration of the car is 15m/s²
