Problem 2-95 Linear Kinematics - Part 2 - (b)

A camera is set up to take photographs of a ball undergoing vertical motion. The camera is \(5.2\; m\) above the ball launcher, which can launch the ball with an initial velocity of \(17 \;m/s\) upward. Assuming that the ball goes straight up and straight down past the camera, at what times will the ball pass the camera?

Accumulated Solution

Correct!

 

When the data is substituted we get:

(A)    \(5.1 = 17t + 4.9t^2\)

(B)    \(-5.1 = 17t - 4.9t^2\)

(C)    \(5.1 = 17t - 4.9t^2\)
