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
