Is speed a scalar or a vector?

A

$s\mathbf{s}s=40i\mathbf{i}i+152j m\frac{15}{2}\mathbf{j}\text{ m}215​j m$

B

Apply it to one identified component, such as vx2=ux2+2axsxv_x^2=u_x^2+2a_xs_xvx2​=ux2​+2ax​sx​.

C

Speed is a scalar.

D

$a\mathbf{a}a=-gj\mathbf{j}j,where, where ,whereg=9.8 m s−2\text{ m s}^{-2} m s−2$.
