Question

A projectile is launched with V0 = 7.6 m/s and initial angle = 1.27 radians above the horizontal. What is the initial horizontal component of the projectile velocity in miles per hour?

Answer 1

The horizontal component is
`v_h = 1.7096 \ m/s`

Step-by-step explanation:

A diagram illustrating the projection is shown on the first uploaded image (from IB Maths Resources from British international school Phuket )

From the question we are told that

The initial velocity is
`v_o = 7.6 \ m/s`

The angle of projection is
`\theta = 1.27 \ rad = 72.77^o`

The horizontal component of this projectile velocity is mathematically represented as

`v_h = v_o * cos (\theta )`

substituting values

`v_h = 7.6 * cos (72.77 )`

`v_h = 1.7096 \ m/s`
