The given figure shows the first attempt of a long jump of an athlete in Olympics.Which of the following factors will MAINLY help him to break his own record in the next attempt?
Correct answer: A. Angle of projection of the athlete
- A. Angle of projection of the athlete
- B. Acceleration of the athlete
- C. Body shape of the athlete
- D. Weight of the athlete
Explanation
A) Angle of projection of the athlete: In projectile motion (like a long jump or shot put, as depicted in the image), the angle at which an object is launched significantly affects its range (horizontal distance). For maximum range, an optimal angle of projection (typically close to 45 degrees in ideal conditions, but can vary depending on release height) is crucial. By optimizing this angle, an athlete can maximize the distance covered and potentially break a record.

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.
