Question

10. A cat starts moving with a uniform acceleration from its position of rest and it noves 25 min is. On applying<br />brakes, it stops aller covering a distance. What is the value of d, if its deceleration is 50/9ms?​

Answer 1

Given that,

The acceleration a=8m/s

2

Initial velocity u=0m/s

We know that,

The displacement in the nth second

=u+a(n−

2

1

)

Now, the displacement in 5th second

=0+8(5−

2

1

)

=36m

Hence, the distance covered by it in fifth second is 36 m
