SUMMARY

The discussion focuses on solving a physics problem involving time (T=1.05s), horizontal distance (Dx=46.1 feet), and angle (15 degrees). To find the horizontal velocity (Vx), vertical velocity (Vy), initial velocity (Vi), and maximum height (Dymax), participants suggest using the equations of motion. Specifically, Vx can be calculated using the formula Vx = Dx / T, while Vy can be derived through trigonometric functions involving the initial velocity and angle. A solid understanding of kinematics is essential to solve the problem effectively.

PREREQUISITES
  • Understanding of kinematics principles
  • Familiarity with trigonometric functions
  • Ability to manipulate equations of motion
  • Knowledge of velocity components
NEXT STEPS
  • Study the equations of motion in physics
  • Learn how to resolve vectors into components
  • Explore the concept of projectile motion
  • Practice solving problems involving trigonometric functions in physics
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in solving projectile motion problems.

I have a problem.

Given: T=1.05s
Dx=46.1feet
Angle=15 Degrees.

I need to find Vx and Vy and Vi and Dymax.

Can anyone help me set up the problem? for each thing I need to find...:frown:
 
Physics news on Phys.org
you can find Vx using T and Dx, then you can find Vy through trigonometry, and then you'll be able to find the rest.
 
Put up some work, so we know what to help you with. If you just need a start, you can go with these equations:

Remember that the distance in the x direction is just the component of velocity in the x direction multiplied by the time it takes.
x=v_{x}t

v_{x}=v_{i}cos(\theta)

v_{y}=v_{i}sin(\theta)

Using those, and a basic knowledge of kinematics you should be able to find everything you need.
