Question

A body starting from rest moving with uniform
acceleration has a displacement of 16 m in
first 4 s and 9 m in first 3 s. The acceleration
of the body is
1) 1 ms22) 2 ms3) 3 ms 24) 4 ms 2​

Answer 1

We know that
S=ut+1/2at^2
So, 16= 0 x 4+ 1/2 x a x 4^2
➡️ 16= 8a
➡️ 2m/s^2 = a

So answer is 2
