Two projectiles are launched at 100 m/s,the angle of elevation for the first being 30° and for the second 60°.Which of the following statements is false?
A)Both projectiles have the same acceleration while in flight.
B)The second projectile has the lower speed at maximum altitude.
C)Both projectiles have the same range.
D)All of the above statements are true.

Question

Quizplus · Accepted Answer

All the statements provided are true based on the principles of projectile motion. Both projectiles experience the same acceleration due to gravity, regardless of their launch angles. The speed at maximum altitude for any projectile is solely its horizontal component of velocity, which is the same for both given they have the same initial speed and complementary angles (30° and 60°). Lastly, projectiles launched at complementary angles (adding up to 90°) with the same speed have the same range, according to the range formula for projectile motion.
