Question

Calculate acceleration of a body which starts from rest and travel 87.5 m 5 sec

Answer 1

To Find:-

• The acceleration of a body / object.

here,

• a = acceleration
• u = initial velocity
• v = final velocity
• s = displacement
• t = time

Solution:-

A . T . Q

u = 0 m/sec

t = 5 sec

s = 87.5 m

So,

By the question,

s = ut +1/2 at²

87.5 =0 × 5 + 1/2 a ( 5² )

87.5 = 1/2 a (25 )

87.5 =a 12.5

87.5/12.5 =a

7 =a

So , 7 m / sec² is acceleration
