Solving for Time and Distance of a Rolling Ball

Click For Summary
SUMMARY

The discussion focuses on calculating the time and distance a ball travels after rolling off a lab bench. Given a horizontal speed of 1.5 m/s and a bench height of 1.2 m, the time to reach the floor is determined using the formula t = √(2y/g), where g is the acceleration due to gravity (approximately 9.81 m/s²). The horizontal distance can then be calculated using the equation x = vt. This results in a clear understanding of projectile motion involving both horizontal and vertical components.

PREREQUISITES
  • Understanding of basic physics concepts, specifically projectile motion.
  • Familiarity with kinematic equations, particularly t = √(2y/g).
  • Knowledge of horizontal and vertical velocity components in motion.
  • Basic mathematical skills for solving equations and performing calculations.
NEXT STEPS
  • Research the effects of air resistance on projectile motion.
  • Learn about the derivation and application of kinematic equations in different scenarios.
  • Explore advanced projectile motion problems involving varying angles of launch.
  • Study the principles of energy conservation in projectile motion.
USEFUL FOR

Students studying physics, educators teaching projectile motion concepts, and anyone interested in applying mathematical equations to real-world motion scenarios.

Homework Statement



Chuck gives a horizontal speed v to a ball that then rolls off a lab bench y meters high. How long a time will it take the ball to reach the floor? How far from a point on the floor directlyt below the edge of the bench will the ball land? Calculate how long and how far for v=1.5 m/s and a bench height of 1.2 m.


Homework Equations



Vx=d/t? only horizontal component of velocity is relevant, right?

The question definitely involves both horizontal and vertical motion.
Better write equations for the y part, too. Usually one for Vy and one for y suffice.
 
hey kcc
aight so when ur doing projectile motion try using this equation to find t:
t = √(2y/g)
and now that u have t u can use the formula V=x/t to find x or arrange it so that its x=vt
:D et voila'
