4.1 Exercise 11

Avg difficulty 2.5

The position of a particle is r→(t)=4.0t2i^−3.0j^+2.0t3k^m.\overset{\rightarrow}{r} \left(t\right) = 4.0 t^{2} \hat{i} - 3.0 \hat{j} + 2.0 t^{3} \hat{k} \text{m} . (a) What is the velocity of the particle at 0 s and at 1.01.0 s? (b) What is the average velocity between 0 s and 1.01.0 s?
