Question

Monica rides her bike off a ramp moving at 4.5 m/s at an angle of 24˚ to the ground.


What is the vertical component of the velocity of Monica and her bike?

Answer 1

As clear from the figure, the vertical projection of the velocity vector $\mathbf{v}$ will be equal:

$$v_y = -v\sin24\degree$$

where $v = 4.5 m/s$ is the module of the velocity vector. Thus, have:

$$v_y = -4.5\sin 24\degree \approx -1.83 m/s$$

Answer. -1.83 m/s.
