6.4 Exercise 33

Avg difficulty 2.5

A 2.0-kg object has a velocity of 4.0i^m/s4.0 \hat{i} \text{m}/\text{s} at t=0.t = 0 . A constant resultant force of (2.0i^+4.0j^)N\left(2.0 \hat{i} + 4.0 \hat{j}\right) \text{N} then acts on the object for 3.0 s. What is the magnitude of the object’s velocity at the end of the 3.0-s interval?
