Initial Velocity and Inclined Plane

Click For Summary
SUMMARY

The discussion centers on a physics problem involving a block pushed up an inclined plane with an initial velocity. The key equation used is v = v(initial) + at, where the final velocity is equal to the initial velocity but in the opposite direction. Participants highlight the need for additional variables, such as the angle of the incline and acceleration, to determine the time at which the block's speed equals its initial velocity again. The lack of numerical values is a significant barrier to solving the problem.

PREREQUISITES
  • Understanding of kinematic equations, specifically v = v(initial) + at
  • Knowledge of forces and Newton's second law, F = ma
  • Familiarity with inclined plane physics and the role of angles
  • Basic algebra skills for manipulating equations
NEXT STEPS
  • Research the effects of incline angles on acceleration in inclined planes
  • Study the relationship between initial velocity and final velocity in motion problems
  • Learn how to apply kinematic equations to solve for time in physics problems
  • Explore examples of motion on inclined planes with numerical values for better understanding
USEFUL FOR

Students studying physics, particularly those focusing on kinematics and inclined plane problems, as well as educators seeking to clarify concepts related to motion and forces.

Homework Statement



A block is given a push up an inclined plane with an initial velocity. At what time will the speed of the block be equal to the initial velocity again? No varialbes are given.

Homework Equations



v= v(initial) + at

The Attempt at a Solution



The final velocity is equal to the initial velocity, but opposite in direction. So, Initial Velocity + Final Velocity = 0. But, I don't know how to find time, because we aren't given any variables to work with.

Looks like you have v, a, and t.

The angle that the incline makes with the horizontal should be involved.
 
So I use the force equation, F=ma, but I still don't know how to solve without any numbers?
