Two projectiles are projected at angles of 20o and 70o respectively with the same initial velocity which one has the longer range;
Correct answer: C. Both have the same range
- A. the one fired at 200
- B. the one fired at 700
- C. Both have the same range
- D. None of these
Explanation
Range for projectiles fired at complementary angles ( angles which add up to 90°) is the same; therefore, option C is correct since 20° + 70° = 90° .

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
