SUMMARY

The basketball player reaches a height of 1.0 m during a jump, and the total time spent in the air is calculated using the equations of motion. The acceleration due to gravity is 9.8 m/s², and the final velocity at the peak of the jump is 0 m/s. The time to reach the peak is determined to be 0.204 seconds, and since the ascent and descent times are equal, the total time in the air is 0.408 seconds.

PREREQUISITES
  • Understanding of SUVAT equations of motion
  • Knowledge of kinematic equations
  • Familiarity with basic physics concepts such as velocity and acceleration
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Study the derivation and application of SUVAT equations
  • Learn how to solve quadratic equations in physics problems
  • Explore the concept of projectile motion and its equations
  • Practice problems involving free fall and vertical motion
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding the principles of motion in sports science.

s = Vt - 0.5 at2
1=0-0.5(-9.8)t^2
1=-0.5(-9.8)t^2
t=0.45 s

Thanks! Is that better?

Looks good.

Great, thanks again! So is this my final answer, or is that just the time it took for him to go *up*?

Well spotted, I'd missed that. Yes just the time to go up. The time to come down will be the same.

Great, thanks!
