Question

The distance covered by the second body when they meet is

• A. 8 m
• B. 16 m
• C. 24 m
• D. 32 m

Answer 1

Answer: (D)

32 m

Let at time t, both bodies will meet.

distance traveled by body A = distance traveled by body B

$u_1\ast t=u_{2}t+\frac{1}{2}a{t}^2$

$8\ast t=0\ast t+\frac{1}{2}\ast 4\ast t^2$

$8t=2t^2$

$t=4s$

Distance covered by body B $=u_2{t}^2+\frac{1}{2}a{t}^2=0\ast t+\frac{1}{2}\ast 4\ast (4{)}^2=32m$

Option 'D' is correct.
