Given, ω = 2 k ^ and r = 2 i ^ + 2 j ^ . Find the linear velocity.

Here, ω = 2 k ^ r = 2 i ^ + 2 j ^ Linear velocity, v = ω × r = 2 k ^ × ( 2 i ^ + 2 j ^ ) = − 4 i ^ + 4 j ^

Given, $ω = 2 \hat{k}$ and $r = 2 \hat{i} + 2 \hat{j}$ . Find the linear velocity.

Options:

Answer:

Solution:

Here, $ω = 2 \hat{k}$ $r = 2 \hat{i} + 2 \hat{j}$ Linear velocity, $v = ω \times r$ $= 2 \hat{k} \times (2 \hat{i} + 2 \hat{j}) = - 4 \hat{i} + 4 \hat{j}$
