Question

A body starting from rest with uniform acceleration travels 40 m in 4 seconds . The velocity of the body after next 16 seconds is ?

Answer 1

Answer:

Explanation:

1ms−2

2ms−2

3ms−2

4ms−2

Answer :

B

Solution :

Distance traveled in 4th second =16−9=7m

Now Dn=u+a2(2n−1) Given u=0

⇒7=0+a2(2×4−1)⇒a=2m/s2.
