4. Calculate the acceleration of a body which starts from rest and travels 87.5 m in 5sec.​

Sagot :

Answer:

the acceleration will be 7m / (s ^ 2)

Explanation:

According to the question,

As the given displacement is 87.5 m

And the time is 5sec.

Where the initial velocity is u=0m/sec

As we have to find the acceleration (a)=?

As we know, s = ut + 1/2 * a * t ^ 2

So now by substituting the values,

87.5 = O * 5 + 1/2 * a * 5 ^ 2

87.5 = 1/2 * a * 25

a = 87.5/12.5

a = 7m / (s ^ 2)

Hence, the acceleration will be 7m / (s ^ 2)
