Answer:

11.2 m/s

Explanation:

Newton's second law:

F = ma

F = m Δv / Δt

2 N = (5 kg) (v − 10 m/s) / 3 s

v = 11.2 m/s

The vertical components of velocity is 10.35 m/s and the horizontal component of velocity is 38.6 m/s

<h3>What are the components of velocity?</h3>

We know that velocity is a vector quantity, a vector often can be resolved into its components. The vertical components is V sinθ while the horizontal component is vcosθ.

Hence;

Vertical component = 40 m/s sin 15 degrees = 10.35 m/s

Horizontal component = 40 cos 15 degrees = 38.6 m/s
