Exam-style question
Try this first
A projectile is launched with an initial velocity of 40 m/s at an angle of 45 degrees. Calculate the vertical component of the initial velocity.
Model answer
What a good answer should say
- The vertical component of the initial velocity is 28.3 m/s.
Explanation
Why this works
This question assesses the understanding of vector resolution into vertical components. The formula used is Vy = V * sin(θ).
The substitution and calculation demonstrate the method clearly, leading to the correct answer.
