Question

Model rocket A is launched at an angle of 70° above the x axis, with an initial velocity of 40 m/s. An identical rocket B is launched under the same conditions at an angle of 90° above the x axis, also with an initial velocity of 40 m/s. Which is the true statement about the horizontal distances the rockets will cover?
A. Rocket A will travel farther horizontally than rocket B.
B. Rocket B will travel farther horizontally than rocket A.
C. The rockets will travel the same horizontal distances but will do so in different amounts of time.
D. There is not enough information to answer this question.

Answer 1

A. Rocket A will travel farther horizontally than rocket B.

This is because from the x axis, 40 m/s at 90 degrees travels directly vertical. 40 m/s at 70 degrees is slightly horizontal, so it will travel further horizontally.
