Question

Find the horizontal and vertical components of a rocket's initial velocity, v = 40 m/sec, if the angle of elevation is 25°. Round your answers to the nearest tenth.

x = 44.1 m/sec; y = 18.7 m/sec

x = 85.8 m/sec; y = 94.6 m/sec

x = 36.3 m/sec; y = 16.9 m/sec

x = 38.0 m/sec; y = 39.0 m/sec

Answer 1

Horizontal: x = 40 cos(25°) ≈ 40(0.9063) = 36.3 m/s
Vertical: y = 40 sin(25°) ≈ 40(0.4226) = 16.9 m/s

So the correct choice is: x = 36.3 m/sec; y = 16.9 m/sec.
