Question

1. A 4-kg object is subjected to two forces, LaTeX: \vec{F}=(2\hat{i}-3\hat{j})N and LaTeX: \vec{F}=(4\hat{i}-11\hat{j})N . The object is at rest at the origin at time t=0 sec.

a. What is the object's acceleration?

b. What is the velocity at t = 3 sec?

c. Where is the object at time t = 3 sec?​

Answer 1

ANSWER:-

a) acceleration of a object

= change in velocity/time taken

change in velocity= final velocity-initial velocity
