Question

Lions are capable of very rapid starts. From rest a lion can sustain an acceleration of 9.5 m/s^ 2 for up to one second. How long would it take a lion to go from rest to a speed of 4.5 m/s?​

Answer 1

➪Given :

⇒u = 0

⇒a = 9.5 m/s²

⇒v = 4.5m/s

➪Solution :

Formula used

• v = u + at

⇒4.5 = 9.5 × t

⇒4.5/9.5 = t

⇒0.47 sec = t
