Question

If a body covers 26 m and 30 m in the 6th and 7th seconds of its motion, then the initial velocity

and acceleration of the body respectively are (assuming acceleration to be uniform)

(A) 4 m s-1 and 4 m s-2 (B) 6 m s-1 and 4 m s-2

(C) 10 m s-1 and 8 m s-2 (D) 0 and 4m s​

Answer 1

Answer:

PLZZZ MARK ME BRAINLIEST ...

Explanation:

Given :

A body covers 26 m and 30 m in the 6th and 7th seconds of its motion .

To Find :

The initial velocity and acceleration of the body .

Solution :

We know , displacement in nth second is given by :

( assuming acceleration to be uniform )

For , n = 6 :

...... ( 1 )

For , n = 7 :

...... ( 2 )

Solving equation 1 and 2

We get :

and u = 4 m/s .

Hence , this is the required solution .
