Question

A body of mass 2 kg is at rest. Two forces of 6 N and 8 N act on the
body at right angles to each other. What is the velocity of the body
after 3 second ?
(A) 10 m/s (B) 15 m/s
(C) 5 m/s
(D) 20 m/s​

Answer 1

Answer:

10m/s

Explanation:

Sn is displacement in nth second

formulA=Sn=u+a(n-1/2)

F=ma

from this find acceleration.

from s=ut+1/2a(t² ) find displacement
