Question

How long will it take a running horse to travel 260 m and attain a speed of 12m/s for rest?
a)43 minutes
b)1200 second
c) 1.2 hour
d)43 hours​

Answer 1

Answer:

1.2hour

Explanation:

Answer 2

the time taken by the horse to travel 260m the speed of 12 metre per second is equal to 43 seconds

Explanation:

• The formula of speed of a particular object is given by,

v²- u²= 2aS

Given,

• the distance that is travelled by the horse  260m

• The maximum speed is 12m/sec

• the horse is at rest in the beginning and hence the initial velocity is equal to zero

• ,So v²= 2aS
• Or a = v²/ 2S = 12²/(2x260)= 18/65m/ sec²

Now by the formula , v= u +at , t= v/a = 12x65/18 = 130/3 sec= 43.33sec

• by approximating we find  the time taken by the horse to cover the particular distance is equal to 40 3.33 seconds
