Question

A lion start from rest and accelerate 2m/second square for 10 second. Calculate final velocity and distance travell

Answer 1

Answer:

Final velocity (v) = 20ms^-1

Distance travelled (S) = 10m

Answer 2

★Given:-

• Intial velocity (u)= 0 ,
• Acceleration (a)= 2m/s²
• Time (t) =10s

★To find:-

• Final velocity and distance travelled.

★Solution:-

Using the first equation of motion,

✦v=u+at

Where,

• v = final velocity
• u = initial velocity = 0
• a = acceleration = 2m/s²
• t = time = 10s

Putting the values,

⇒v  =0+2(10)

⇒ v = 20m/s

Using 3rd equation of motion,  

✦v²=u²+2as

Putting values,

⇒v²=u²+2as

⇒(20)² = 0 + 2× 2×s

⇒400= 4s

⇒s=400/4

⇒ s= 100m

Therefore,

Final velocity is 20m/sec  & Distance is 100m.
