    Figure Velocity
AI Thread Summary
The discussion revolves around calculating the velocity of a baseball thrown straight up with an initial velocity of 10.0 m/s and an acceleration of 9.81 m/s² downward. To find the velocity after 0.50 seconds and 1.50 seconds, the kinematic equation v = u + at is suggested. Participants express frustration with understanding the concept of velocity and seek clarification on the formulas involved. The conversation emphasizes the importance of applying kinematic equations to solve the problem effectively. Overall, the thread highlights common challenges in grasping velocity calculations in physics.

Velocity question...i can't figure it out :(

A person throws a baseball straight up from the ground. The baseball leaves the persons hand with an initial velocity of 10.0 m/s [up]. The acceleration of the ball is 9.81 m/s 2 [down]. Assume up as the positive direction.

a. what is the velocity of the baseball after 0.50 s?
b. what is the velocity of the baseball after 1.50 s?

THANK YOU SOOO MUCH IN ADVANCE!

How would you go about solving the problem?

What is it you are stuck on?

For instance I know how to figure it out, but I'm not getting the grade, nor am I taking your tests.

How do you think to go about it?
 


I seriously have no idea...
this whole velocity is driving me crazy..
can you explain?
 


well, you know the Kinematical equations.
v = u + at
s = ut + 0.5at^2
v^2 = u^2 + 2as
Use them

let's start by asking you this : what formula's for velocity do you know ?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
