Question

options: 5 m/s², 10m/s², 15m/s², 20m/s²​

Answer 1

Answer

• Rate of change of velocity is called as acceleration
• Acceleration is given by the formula, a = (v_final - v_initial)/time

⇒ a = (v_final - v_initial)/time

⇒ a = (40-0)/4

⇒ a = 40/4

⇒ a = 10 m/s²

∴ The acceleration of the body is 10 m/s²
