The span of the broad jump depends upon_______________?
Correct answer: C. Angle of projection
- A. Mass of the jumper
- B. Height of jump
- C. Angle of projection
- D. None
Explanation
For a projectile launched and landing at the same level, the horizontal range depends on the projection angle through R = u² sin(2θ)/g. Thus, for a given launch speed, changing the angle changes the span of the broad jump. The likely mistake is choosing mass, although mass cancels from the projectile equations when air resistance is neglected.

About Projectile Motion
Projectile motion combines uniform horizontal motion with vertically accelerated motion under gravity, assuming air resistance is neglected. Questions use the components of initial velocity to find time of flight, maximum height, horizontal range and position, while distinguishing projectile motion from general circular or one dimensional motion.
