To avoid a collision what is your reaction time?
Homework Statement As you are driving with a velocity of 75 km/h [N], you suddenly realize that there is a stalled vehicle in your lane 48.0m directly ahead. You react, applying the brakes to provide an acceleration of 4.80 m/s^2 [S]. If you managed to avoid a collision what was your...- KaseyK

Vertical Jump Analysis: Calculating Time and Take-Off Speed
No I don't need to solve it using kinematics. I can use any way I want, I just can't figure either way out...ugh.- KaseyK

Vertical Jump Analysis: Calculating Time and Take-Off Speed
Okay did I at least use the right kinematic equation? Is there anything else you can hint to, to send me in the right direction? Thanks- KaseyK

Vertical Jump Analysis: Calculating Time and Take-Off Speed
Homework Statement A certain volleyball player can jump to a vertical height of 85 cm while spiking the volleyball. Homework Equations (a) How long is the player in the air for? (b) What is the player's vertical take-off speed? The Attempt at a Solution Firstly I converted 85...- KaseyK

Average Speed - isn't this average velocity?
Thank you very much. That is so much more clearer. I did have an additional question if you don't mind. The (b) part asks me to calculate the final position of the ball. The answer is 0.32m [N]. I was trying to use one of the various kinematic equations however I feel like I'm missing...- KaseyK

Average Speed - isn't this average velocity?
A billiard ball travels 0.44m [S] from its original position, bounces off another ball and travels 0.88m [N], then bounces off the edge of the billiard table coming to rest 0.12m from that edge. The entire motion is one-dimensional and takes 2.4s. (a) calculate the average speed of the ball...- KaseyK

How Do You Calculate the Final Velocity of a Skydiver?
This question was actually a 3 part question. I answered (a) and (b) correctly however I can't figure out how to calculate the 'final velocity of the skydiver'. Here are the givens: x axis v1 - 90 m/s acceleration - zero delta t - 10.6 seconds delta d - 958.5 m Y axis v1 = 0 delta t...- KaseyK
