At $t = 1 sec$ ., a particle is at $(1, 0, 0)$ . It moves towards $(4, 4, 12)$ with a constant speed of $65 m / s$ . The position of the particle is measured in metres and the time in sec. Assuming constant velocity, the position of the particle at $t = 3 s$ is :

Options:

Answer:

Solution:

$S = V t$

$r_{f} - \hat{i} = \frac{65 ( 3 i ^ + 4 j ^ + 12 k ^ )}{13} 3 = 30 \hat{i} + 40 \hat{j} + 120 \hat{k}$
